Activity implementation pop-up menu, activity pop-up menu

Activity is set to a dialog floating window and style, which can be used to complete functions that cannot be implemented by dialog. For example, the Activity can be suspended on the desktop of a mobile phone and is not affected by the activity interface, this indicates that the floating window is not affiliated with the Activity interface, that is, it is affiliated with the process of starting its application. For example, the application process where 360App is located disappears only when it is killed.

First:

1. java code:

MenuActivity. java

Package com. xiebao. aboutus; import android. OS. build; import android. OS. bundle; import android. view. gravity; import android. view. view; import android. view. window; import android. view. windowManager; import android. widget. textView; import com. xiebao. r; import com. xiebao. core. toastUtils; import com. xiebao. fatherclass. fatherActivity; public class MenuActivity extends FatherActivity implementsView. onClickListener {@ Overrideprotected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); this. requestWindowFeature (Window.

2. layout file: activity_menu_layout.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:background="@color/menu_color"    android:gravity="center"    android:orientation="vertical"    android:padding="10dp" >    <TextView        android:id="@+id/back_home"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="@drawable/menu_backgroud_select"        android:gravity="center"        android:padding="10dp"        android:text="@string/back_text"        android:textColor="@color/white"        android:textSize="20sp" />    <View        android:layout_width="match_parent"        android:layout_height="1dp"        android:background="@color/list_divider_color" />    <TextView        android:id="@+id/about_xiebao"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="@drawable/menu_backgroud_select"        android:gravity="center"        android:padding="10dp"        android:text="@string/about_xiebao"        android:textColor="@color/white"        android:textSize="20sp" />    <View        android:layout_width="match_parent"        android:layout_height="1dp"        android:background="@color/list_divider_color" />    <TextView        android:id="@+id/help_center"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="@drawable/menu_backgroud_select"        android:gravity="center"        android:padding="10dp"        android:text="@string/help_center"        android:textColor="@color/white"        android:textSize="20sp" />    <View        android:layout_width="match_parent"        android:layout_height="1dp"        android:background="@color/list_divider_color" />    <TextView        android:id="@+id/feed_back"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="@drawable/menu_backgroud_select"        android:gravity="center"        android:padding="10dp"        android:text="@string/feed_back"        android:textColor="@color/white"        android:textSize="20sp" /></LinearLayout>
