}
需要注意的是：1.本人一开始用PopupWindow就曾经报错： "Unable to add window -- token null is not valid"，原因在stackoverflow上找到：To avoid BadTokenException, you need to defer showing the popup until after all the lifecycle methods are called (-> activity window is displayed)，简而言之就是要在布局全部加载完之后再去加载PopupWindow,显示PopupWindow过早就会直接crash.
2.在Activity取出string资源文件值，textView.setText(R.string.XXX)是错误的写法应g改为-->textView.setText(getString(R.string.xxx))或者getResources().getString(R.string.xxx)，原因：http://stackoverflow.com/questions/11536326/android-settext-r-string-values
（第一句一语道破天机，R.string.xxx仅仅是资源的ID，所以R.String.xxx得到的是资源的编号）
Android Popupwindow 拖动
关于View的拖动你们应该比较了解了，好比对一个控件IamgeView拖动，或者一个视图View拖动，实现方式也很容易，继承OnTouchListener接口，而后重写onTouch方法，在触屏事件进行处理便可。可是Popupwindow如何实现拖动呢，咱们都知道它和普通的View不同，由于它不是继承于View类的，可是它的实现倒是和View密切相关的，由于咱们都知道Android视图的显示都是由View来处理的，因此必定离不开它。从Popupwindow的实现就能够看出来，ide
import com.android.internal.R; import android.content.Context; import android.content.res.Resources; import android.content.res.TypedArray; import android.graphics.PixelFormat; import android.graphics.Rect; import android.graphics.drawable.Drawable; import android.graphics.drawable.StateListDrawable; import android.os.Build; import android.os.IBinder; import android.util.AttributeSet; import android.view.Gravity; import android.view.KeyEvent; import android.view.MotionEvent; import android.view.View; import android.view.View.OnTouchListener; import android.view.ViewGroup; import android.view.ViewTreeObserver; import android.view.ViewTreeObserver.OnScrollChangedListener; import android.view.WindowManager; import java.lang.ref.WeakReference;上面是它的导包状况，基本上不是和View相关，就是和绘图相关。所以关于Popupwindow的拖动这一块，也和View有联系。首先看一下它的API，看一看有没有和View移动、变化相关的方法，果真在最后有几个update()方法，以下：
update()方法用来更新Popupwindow的位置和大小的，那么问题就好解决了。看代码：布局
package com.example.drag_and_drop_movablepopupwindow;
import android.support.v7.app.ActionBaractivity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.PopupWindow;
import android.widget.TextView;
public class MainActivity extends ActionBaractivity {
private Button btnopenPopup;
private int mCurrentX;
private int mCurrentY;
private PopupWindow mPopup;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnopenPopup = (Button) findViewById(R.id.openpopup);
btnopenPopup.setonClickListener(new Button.OnClickListener() {
@Override
public void onClick(View arg0) {
creatPopubWindow_1();
}
});
}
/**
* 1
*/
private void creatPopubWindow_1() {
LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup, null);
final PopupWindow popupWindow = new PopupWindow(popupView,
200, 200);
Button btndismiss = (Button) popupView.findViewById(R.id.dismiss);
btndismiss.setonClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
popupWindow.dismiss();
}
});
popupWindow.showAsDropDown(btnopenPopup, 50, 50);
popupView.setonTouchListener(new OnTouchListener() {
int orgX, orgY;
int offsetX, offsetY;
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
orgX = (int) event.getX();
orgY = (int) event.getY();
break;
case MotionEvent.ACTION_MOVE:
offsetX = (int) event.getRawX() - orgX;
offsetY = (int) event.getRawY() - orgY;
popupWindow.update(offsetX, offsetY, -1, -1, true);
break;
}
return true;
}
});
}
}
效果如图：ui
首先对Popupwindow设置触摸事件，而后在回调方法中进行计算，若是手指拖动了Popupwindow，那么就调用update()方法来更新它的位置。有些同窗可能不太理解参数-1是什么意思，在上面的API中，写明的是宽和高，这里怎么变成-1了呢，看一下Popupwindow源代码就明白了。this
/**
* <p>Updates the position and the dimension of the popup window. Width and
* height can be set to -1 to update location only. Calling this function
* also updates the window with the current popup state as
* described for {@link #update()}.</p>
*
* @param x the new x location
* @param y the new y location
* @param width the new width, can be -1 to ignore
* @param height the new height, can be -1 to ignore
* @param force reposition the window even if the specified position
* already seems to correspond to the LayoutParams
*/
public void update(int x, int y, int width, int height, boolean force) {
if (width != -1) {
mLastWidth = width;
setWidth(width);
}
if (height != -1) {
mLastHeight = height;
setHeight(height);
}
if (!isShowing() || mContentView == null) {
return;
}
WindowManager.LayoutParams p = (WindowManager.LayoutParams) mPopupView.getLayoutParams();
boolean update = force;
final int finalWidth = mWidthMode < 0 ? mWidthMode : mLastWidth;
if (width != -1 && p.width != finalWidth) {
p.width = mLastWidth = finalWidth;
update = true;
}
final int finalHeight = mHeightMode < 0 ? mHeightMode : mLastHeight;
if (height != -1 && p.height != finalHeight) {
p.height = mLastHeight = finalHeight;
update = true;
}
if (p.x != x) {
p.x = x;
update = true;
}
if (p.y != y) {
p.y = y;
update = true;
}
final int newAnim = computeAnimationResource();
if (newAnim != p.windowAnimations) {
p.windowAnimations = newAnim;
update = true;
}
final int newFlags = computeFlags(p.flags);
if (newFlags != p.flags) {
p.flags = newFlags;
update = true;
}
if (update) {
setLayoutDirectionFromAnchor();
mWindowManager.updateViewLayout(mPopupView, p);
}
}
前两个if判断已经说得很清楚了，若是参数是-1的话，就不改变Popupwindow的大小了，由于咱们只是移动位置，因此才这样写。那关于Popupwindow的移动最后是怎么实现的呢，能够看出就是调用WindowManager的updateViewLayout()方法，这个方法在WindowManager中并无实现，它是ViewManager接口里面的方法，WindowManager继承了ViewManager。说到ViewManager，它里面定义的方法都很经常使用，看代码：
/** Interface to let you add and remove child views to an Activity. To get an instance
* of this class, call {@link android.content.Context#getSystemService(java.lang.String) Context.getSystemService()}.
*/
public interface ViewManager
{
/**
* Assign the passed LayoutParams to the passed View and add the view to the window.
* <p>Throws {@link android.view.WindowManager.BadTokenException} for certain programming
* errors, such as adding a second view to a window without removing the first view.
* <p>Throws {@link android.view.WindowManager.InvaliddisplayException} if the window is on a

*/
public void addView(View view, ViewGroup.LayoutParams params);
public void updateViewLayout(View view, ViewGroup.LayoutParams params);
public void removeView(View view);
}
这下你们应该明了，咱们常常用的addView、removeView方法就是在这里面定义的，那么谁去实现呢？就是Layout控件，好比LinearLayout、RelativeLayout等，因此咱们刚才用的updateViewLayout()方法也是在xml布局文件中的layout定义好的。
Android PopupWindow实现右侧、左侧和底部弹出菜单
本教程为大家分享了Android PopupWindow弹出菜单的具体代码，供大家参考，具体内容如下
项目代码：http://xiazai.jb51.net/201611/yuanma/PopupLeftMenu(jb51.net).rar
项目SDK是5.1，建议将代码拷到自己的工程中去
代码如下：
MainActivity类：
package com.example.popupleftmenu;
import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.view.Gravity;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnTouchListener;
import android.view.ViewGroup.LayoutParams;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.PopupWindow;
import android.widget.Toast;
public class MainActivity extends Activity {
private Context context = null;
private PopupWindow popupWindow;
private int from = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context = this;
setContentView(R.layout.activity_main);
Button popLeftBtn = (Button)findViewById(R.id.pop_left_btn);
Button popRightBtn = (Button)findViewById(R.id.pop_right_btn);
Button popBottomBtn = (Button)findViewById(R.id.pop_bottom_btn);
popLeftBtn.setonClickListener(popClick);
popRightBtn.setonClickListener(popClick);
popBottomBtn.setonClickListener(popClick);
}
OnClickListener popClick = new OnClickListener() {
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.pop_left_btn:{
from = Location.LEFT.ordinal();
break;
}
case R.id.pop_right_btn:{
from = Location.RIGHT.ordinal();
break;
}
case R.id.pop_bottom_btn:{
from = Location.BottOM.ordinal();
break;
}
}
//调用此方法，menu不会顶置
//popupWindow.showAsDropDown(v);
initPopupWindow();
}
};
/**
* 添加新笔记时弹出的popWin关闭的事件，主要是为了将背景透明度改回来
*
*/
class popupdismissListener implements PopupWindow.OndismissListener{
@Override
public void ondismiss() {
backgroundAlpha(1f);
}
}
protected void initPopupWindow(){
View popupWindowView = getLayoutInflater().inflate(R.layout.pop,null);
//内容，高度，宽度
if(Location.BottOM.ordinal() == from){
popupWindow = new PopupWindow(popupWindowView,LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT,true);
}else{
popupWindow = new PopupWindow(popupWindowView,true);
}
//动画效果
if(Location.LEFT.ordinal() == from){
popupWindow.setAnimationStyle(R.style.AnimationLeftFade);
}else if(Location.RIGHT.ordinal() == from){
popupWindow.setAnimationStyle(R.style.AnimationRightFade);
}else if(Location.BottOM.ordinal() == from){
popupWindow.setAnimationStyle(R.style.AnimationBottomFade);
}
//菜单背景色
ColorDrawable dw = new ColorDrawable(0xffffffff);
popupWindow.setBackgroundDrawable(dw);
//宽度
//popupWindow.setWidth(LayoutParams.WRAP_CONTENT);
//高度
//popupWindow.setHeight(LayoutParams.FILL_PARENT);
//显示位置
if(Location.LEFT.ordinal() == from){
popupWindow.showAtLocation(getLayoutInflater().inflate(R.layout.activity_main,null),Gravity.LEFT,500);
}else if(Location.RIGHT.ordinal() == from){
popupWindow.showAtLocation(getLayoutInflater().inflate(R.layout.activity_main,Gravity.RIGHT,500);
}else if(Location.BottOM.ordinal() == from){
popupWindow.showAtLocation(getLayoutInflater().inflate(R.layout.activity_main,Gravity.BottOM|Gravity.CENTER_HORIZONTAL,0);
}
//设置背景半透明
backgroundAlpha(0.5f);
//关闭事件
popupWindow.setondismissListener(new popupdismissListener());
popupWindowView.setonTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v,MotionEvent event) {
/*if( popupWindow!=null && popupWindow.isShowing()){
popupWindow.dismiss();
popupWindow=null;
}*/
// 这里如果返回true的话，touch事件将被拦截
// 拦截后 PopupWindow的onTouchEvent不被调用，这样点击外部区域无法dismiss
return false;
}
});
Button open = (Button)popupWindowView.findViewById(R.id.open);
Button save = (Button)popupWindowView.findViewById(R.id.save);
Button close = (Button)popupWindowView.findViewById(R.id.close);
open.setonClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context,"Open",Toast.LENGTH_LONG).show();
popupWindow.dismiss();
}
});
save.setonClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context,Toast.LENGTH_LONG).show();
popupWindow.dismiss();
}
});
close.setonClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context,Toast.LENGTH_LONG).show();
popupWindow.dismiss();
}
});
}
/**
* 设置添加屏幕的背景透明度
* @param bgalpha
*/
public void backgroundAlpha(float bgalpha)
{
WindowManager.LayoutParams lp = getwindow().getAttributes();
lp.alpha = bgalpha; //0.0-1.0
getwindow().setAttributes(lp);
}
/**
* 菜单弹出方向
*
*/
public enum Location {
LEFT,RIGHT,TOP,BottOM;
}
}
两个布局文件：
1.activity_main.xml，就三个Button
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <Button android:id="@+id/pop_left_btn" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/pop_left"/> <Button android:id="@+id/pop_right_btn" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/pop_right"/> <Button android:id="@+id/pop_bottom_btn" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/pop_bottom"/> </LinearLayout>
2. pop.xml，也是三个Button，可以自己修改
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <!-- <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:background="#ffffff"> --> <Button android:id="@+id/open" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/open"/> <Button android:id="@+id/save" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/save"/> <Button android:id="@+id/close" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/close"/> <!-- </LinearLayout> --> </LinearLayout>
strings.xml
<string name="pop_left">弹出左侧菜单</string> <string name="pop_right">弹出右侧菜单</string> <string name="pop_bottom">弹出底部菜单</string> <string name="open">打开</string> <string name="save">保存</string> <string name="close">关闭</string>
styles.xml
<style name="AnimationLeftFade"> <item name="android:windowEnteranimation">@anim/in_lefttoright</item> <item name="android:windowExitAnimation">@anim/out_righttoleft</item> </style> <style name="AnimationRightFade"> <item name="android:windowEnteranimation">@anim/in_righttoleft</item> <item name="android:windowExitAnimation">@anim/out_lefttoright</item> </style> <style name="AnimationBottomFade"> <item name="android:windowEnteranimation">@anim/in_bottomtotop</item> <item name="android:windowExitAnimation">@anim/out_toptobottom</item> </style>
左边弹出菜单动画文件：
in_lefttoright.xml：从左边入
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromXDelta="-100%" android:toXDelta="0" android:duration="500"/> </set>
out_righttoleft.xml：从右边出
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromXDelta="0" android:toXDelta="-100%" android:duration="500"/> </set>
其他动画文件自己参考写，就是fromXDelta， fromYDelta， toXDelta和toYDelta使用。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持编程小技巧。
