我有一个弹出窗口,应该显示两个按钮和一个带有这个 xml 的 textview:
<?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:id="@+id/pe"
android:paddingTop="100dp"
android:paddingBottom="100dp"
android:paddingLeft="180dp"
android:paddingRight="180dp"
android:background="#444444"
android:orientation="vertical" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textSize="26dp"
android:text="Are you sure?" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="@+id/bYesClear"
android:layout_width="86dp"
android:layout_height="wrap_content"
android:text="Yes" />
<Button
android:id="@+id/bNoClear"
android:layout_width="86dp"
android:layout_height="wrap_content"
android:text="No" />
</LinearLayout>
</LinearLayout>
这段代码正在调用它:
private PopupWindow pw;
private void initiatePopupWindow() {
try {
LayoutInflater inflater = (LayoutInflater) Options.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.popupareyousure, (ViewGroup) findViewById(R.id.pe));
pw = new PopupWindow(layout, 470, 300, true);
pw.showAtLocation(layout, Gravity.CENTER, 0, 0);
yesClearButton = (Button) layout.findViewById(R.id.bYesClear);
noClearButton = (Button) layout.findViewById(R.id.bNoClear);
yesClearButton.setOnClickListener(this);
noClearButton.setOnClickListener(this);
} catch (Exception e) {
e.printStackTrace();
}
}
它确实以正确的大小显示弹出窗口,但是,它不显示文本视图,也不显示其中的按钮。
