Example code of long press photo pop-up right-click menu function in Android

Scene Effect

Note:

realization

Change the layout to LinearLayout and set it as a vertical layout through Android: orientation = "vertical" >.

Then add an ImageView and set the ID property and the image source.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical"
  tools:context=".LongClickActivity">
  <ImageView
    android:id="@+id/image"
    android:src="@drawable/dog"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>
</LinearLayout>

Then come to the activity. First override the oncreatecontextmenu method in the activity. This method can add a menu and add menu items

 //在activity中重写onCreateContextMenu菜单，为菜单添加选项值
  @Override
  public void onCreateContextMenu(ContextMenu menu,View v,ContextMenu.ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu,v,menuInfo);
    menu.add("收藏");
    menu.add("举报");
  }

Then register the long press event into the menu in the oncreate method and open the menu.

 @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_long_click);
    //将长按事件注册到菜单中，并打开菜单
    ImageView imageView = (ImageView) findViewById(R.id.image);
    imageView.setOnLongClickListener(new View.OnLongClickListener() {
      @Override
      public boolean onLongClick(View v) {
        //注册菜单
        registerForContextMenu(v);
        //打开菜单
        openContextMenu(v);
        return true;
      }
    });
  }

        registerForContextMenu(v);
        //打开菜单
        openContextMenu(v);
        return true;
      }
    });

  //在activity中重写onCreateContextMenu菜单，为菜单添加选项值
  @Override
  public void onCreateContextMenu(ContextMenu menu,menuInfo);
    menu.add("收藏");
    menu.add("举报");
  }
}
