我PopupWindow
通过单击以下菜单项使用以下代码创建背景较暗的Toolbar
:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.btn_1:
Log.i(TAG, "Clicked Button 1");
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup_window, null);
final PopupWindow popupWindow = new PopupWindow(popupView, Toolbar.LayoutParams.MATCH_PARENT, Toolbar.LayoutParams.MATCH_PARENT);
Button btnDismiss = (Button)popupView.findViewById(R.id.btn_dismiss);
btnDismiss.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
popupWindow.dismiss();
}
});
popupWindow.showAtLocation(popupView, Gravity.CENTER, 0, 0);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
但是,我要在昏暗的背景下排除动作栏/工具栏。我该如何实现?
的布局PopupView
如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:id="@+id/bac_dim_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#C0000000"
android:visibility="visible" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_margin="1dp"
android:background="@android:color/darker_gray">
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_margin="20dp">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="It's a PopupWindow" />
<Button
android:id="@+id/btn_dismiss"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Dismiss" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
</LinearLayout>
如果您希望弹出窗口以暗淡的背景显示,除了ToolBar / ActionBar
在这里,我尝试设置弹出窗口的位置。获取状态栏和导航栏的高度并将Y位置设置为弹出窗口
int actionBarHeight = 0;
View popupView = LayoutInflater.from(getActivity()).inflate(R.layout.popup_, null);
final PopupWindow popupWindow = new PopupWindow(popupView, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
actionBarHeight = getNavigationBarHeight(getActivity(), Configuration.ORIENTATION_PORTRAIT);
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
actionBarHeight = actionBarHeight + getResources().getDimensionPixelSize(resourceId);
}
Button btnDismiss = (Button) popupView.findViewById(R.id.btn_dismiss);
btnDismiss.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
popupWindow.dismiss();
}
});
popupWindow.showAsDropDown(popupView, 0, actionBarHeight);
如您在评论中所述,显示弹出窗口的另一种方法。
在布局中采用一个隐藏的控件(TextView),该控件将与顶部对齐。将TextView的位置和分配给Y的位置弹出窗口
public class MyPopupTest extends Fragment{
public static final String TAG = "MyPopupTest";
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.home_screen_slider, container, false);
}
@Override
public void onViewCreated(final View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
view.findViewById(R.id.btnSelect).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showPopup(view);
}
});
}
public void showPopup(View view) {
View popupView = LayoutInflater.from(getActivity()).inflate(R.layout.popup_, null);
final PopupWindow popupWindow = new PopupWindow(popupView, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
Button btnDismiss = (Button) popupView.findViewById(R.id.btn_dismiss);
btnDismiss.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
popupWindow.dismiss();
}
});
int[] locationOfHiddenTextView = new int[2];
view.findViewById(R.id.hiddenTopTextView).getLocationOnScreen(locationOfHiddenTextView);
//Give Position as a start point for popup
popupWindow.showAsDropDown(popupView, 0, locationOfHiddenTextView[1]);
}
}
要显示的片段的XML文件
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/relative_home"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffc699">
<TextView
android:id="@+id/hiddenTopTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:visibility="gone" />
<Button
android:id="@+id/btnSelect"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Show Popup" />
</RelativeLayout>
