日常开发过程中对于PopupWindown的使用也是比较多的。这里给大家展示一下PopupWindow的使用。

修改activity_main.xml布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="${relativePackage}.${activityClass}" > <RelativeLayout android:layout_width="match_parent" android:layout_height="50dip" android:background="@android:color/holo_blue_dark"> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="10dip" android:background="@drawable/ic_launcher" /> <ImageView android:id="@+id/rl_more" android:layout_width="wrap_content" android:layout_height="match_parent" android:background="@drawable/ability_show_item_bg" android:paddingLeft="15dp" android:paddingRight="5dp" android:layout_alignParentRight="true" android:src="@drawable/actionbar_more_icon" /> </RelativeLayout> </RelativeLayout>

新建popup_window.xml布局文件

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@android:color/white" android:gravity="center_horizontal" android:orientation="vertical" > <TextView android:id="@+id/settings" android:layout_width="match_parent" android:layout_height="45dp" android:gravity="center" android:padding="12dp" android:text="设置" android:textSize="16sp" /> <View android:layout_width="match_parent" android:layout_height="1dp" android:background="#BDBDBD" /> <TextView android:id="@+id/about" android:layout_width="match_parent" android:layout_height="45dp" android:gravity="center" android:padding="12dp" android:text="关于" android:textSize="16sp" /> <View android:layout_width="match_parent" android:layout_height="1dp" android:background="#BDBDBD" /> <TextView android:id="@+id/ability_logout" android:layout_width="match_parent" android:layout_height="45dp" android:gravity="center" android:padding="12dp" android:text="退出" android:textSize="16sp" /> </LinearLayout>

自定义PopupWindow类PopWindow

package com.syz.mypopupwindow; import android.app.Activity; import android.content.Context; import android.graphics.drawable.ColorDrawable; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup.LayoutParams; import android.widget.PopupWindow; /** * <p>Title:PopWindow</p> * <p>Description: 自定义PopupWindow</p> * @author syz * @date 2016-3-14 */ public class PopWindow extends PopupWindow{ private View conentView; public PopWindow(final Activity context){ LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); conentView = inflater.inflate(R.layout.popup_window, null); int h = context.getWindowManager().getDefaultDisplay().getHeight(); int w = context.getWindowManager().getDefaultDisplay().getWidth(); // 设置SelectPicPopupWindow的View this.setContentView(conentView); // 设置SelectPicPopupWindow弹出窗体的宽 this.setWidth(w / 2 + 40); // 设置SelectPicPopupWindow弹出窗体的高 this.setHeight(LayoutParams.WRAP_CONTENT); // 设置SelectPicPopupWindow弹出窗体可点击 this.setFocusable(true); this.setOutsideTouchable(true); // 刷新状态 this.update(); // 实例化一个ColorDrawable颜色为半透明 ColorDrawable dw = new ColorDrawable(0000000000); // 点back键和其他地方使其消失,设置了这个才能触发OnDismisslistener ，设置其他控件变化等操作 this.setBackgroundDrawable(dw); // mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog); // 设置SelectPicPopupWindow弹出窗体动画效果 this.setAnimationStyle(R.style.AnimationPreview); conentView.findViewById(R.id.about).setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { //do something you need here PopWindow.this.dismiss(); } }); conentView.findViewById(R.id.ability_logout).setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { // do something before signing out context.finish(); PopWindow.this.dismiss(); } }); conentView.findViewById(R.id.settings).setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { // do something you need here PopWindow.this.dismiss(); } }); } /** * 显示popupWindow * * @param parent */ public void showPopupWindow(View parent) { if (!this.isShowing()) { // 以下拉方式显示popupwindow this.showAsDropDown(parent, parent.getLayoutParams().width / 2, 5); } else { this.dismiss(); } } }

添加自定义PopupWindow所需的style

AnimationPreview

<style name="AnimationPreview"> <item name="android:windowEnterAnimation">@anim/fade_in</item> <item name="android:windowExitAnimation">@anim/fade_out</item> </style>

添加style所需的动画

fade_in.xml

<?xml version="1.0" encoding="utf-8"?> <!-- 左上角扩大--> <scale xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_decelerate_interpolator" android:fromXScale="0.001" android:toXScale="1.0" android:fromYScale="0.001" android:toYScale="1.0" android:pivotX="100%" android:pivotY="10%" android:duration="200" />

fade_out.xml

<?xml version="1.0" encoding="utf-8"?> <!-- 左上角缩小 --> <scale xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_decelerate_interpolator" android:fromXScale="1.0" android:toXScale="0.001" android:fromYScale="1.0" android:toYScale="0.001" android:pivotX="100%" android:pivotY="10%" android:duration="200" />

最后在MainActivity类中使用

package com.syz.mypopupwindow; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; public class MainActivity extends Activity implements OnClickListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); findViewById(R.id.rl_more).setOnClickListener(this); } @Override public void onClick(View v) { if(v.getId() == R.id.rl_more){ PopWindow popWindow = new PopWindow(this); popWindow.showPopupWindow(findViewById(R.id.rl_more)); } } }
