你可以使用以下代码来实现弹出PopupWindow,并添加背景遮罩以及点击遮罩时弹窗消失。
首先,在你的布局文件(例如activity_main.xml)中添加一个透明的背景遮罩视图:
```xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Your main layout content here -->
<View
android:id="@+id/background_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent" />
</FrameLayout>
```
然后,在你的Activity或Fragment中的代码中,添加以下方法来显示和隐藏PopupWindow:
```java
public class MainActivity extends AppCompatActivity {
private PopupWindow popupWindow;
private View backgroundView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
backgroundView = findViewById(R.id.background_view);
// 设置背景遮罩点击事件
backgroundView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismissPopupWindow();
}
});
// 显示PopupWindow
showPopupWindow();
}
private void showPopupWindow() {
// 创建PopupWindow视图
LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = inflater.inflate(R.layout.popup_window, null);
// 设置PopupWindow的属性
popupWindow = new PopupWindow(popupView, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setFocusable(true);
popupWindow.setOutsideTouchable(true);
popupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
// 显示PopupWindow
popupWindow.showAtLocation(findViewById(R.id.main_layout), Gravity.CENTER, 0, 0);
}
private void dismissPopupWindow() {
// 隐藏PopupWindow
if (popupWindow != null && popupWindow.isShowing()) {
popupWindow.dismiss();
}
}
}
```
最后,创建一个popup_window.xml资源文件来定义PopupWindow的布局:
```xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:color/white"
android:orientation="vertical"
android:padding="16dp">
<!-- Your PopupWindow content here -->
</LinearLayout>
```
这样,当你的Activity或Fragment启动时,PopupWindow将显示在屏幕中央,并且点击背景遮罩时PopupWindow将被隐藏。请根据你的需要修改布局和样式。
