Android弹出式菜单填写父母

Question

我尝试设置我的弹出式菜单以填充网格上的孔项目。目前它看起来像附在第一张照片上，下一张是我想要的效果。

我的代码：

private void showPopupMenu(View view) { 
    // inflate menu 
    ContextThemeWrapper ctw = new ContextThemeWrapper(context, R.style.PopupMenu); 

    PopupMenu popup = new PopupMenu(ctw, view); 

    Menu menu = popup.getMenu(); 
    menu.add(Menu.NONE, 1, Menu.NONE, "Remove"); 
    menu.add(Menu.NONE, 2, Menu.NONE, "Block"); 

    popup.setOnMenuItemClickListener(new MyMenuItemClickListener()); 
    popup.show(); 
} 

可否请你点我到正确的方向，实现从项目的效果呢？

Answer 1

使用PopupWindow试试这个

popup.getWindow().getAttributes().height = ViewGroup.LayoutParams.MATCH_PARENT; 
    popup.getWindow().getAttributes().width = ViewGroup.LayoutParams.MATCH_PARENT;

演示应用为您的需求量的。 Preview

您可以在其中添加列表或根据需要对其进行自定义。 MainActivity

public class MainActivity extends Activity { 

    boolean isClicked = true; 
    PopupWindow popUpWindow; 
    RelativeLayout relative; 
    ImageView btnClickHere; 


    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     relative = (RelativeLayout) findViewById(R.id.relative); 
     popUpWindow = new PopupWindow(this); 
     popUpWindow.setContentView(getLayoutInflater().inflate(R.layout.popup_design, null)); 
     popUpWindow.getContentView().findViewById(R.id.textViewa).setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Toast.makeText(MainActivity.this, "PopItemClicked", Toast.LENGTH_LONG).show(); 
      } 
     }); 

     btnClickHere = (ImageView) findViewById(R.id.imageView); 
     btnClickHere.setOnClickListener(new View.OnClickListener() { 

      public void onClick(View v) { 
       if (isClicked) { 
        isClicked = false; 
        popUpWindow.setHeight(relative.getHeight()); 
        popUpWindow.setWidth(relative.getWidth()); 
        popUpWindow.showAsDropDown(relative, 0, -relative.getHeight()); 
       } else { 
        isClicked = true; 
        popUpWindow.dismiss(); 
       } 
      } 
     }); 
    } 
}
