Android弹出菜单填充父级

Question

我尝试设置我的弹出菜单以填充网格上的洞项目。目前它看起来像附加的第一张图片，下一张图片是我想要的效果。

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();
}

请您指出正确的方向来实现项目的效果吗？

使用PopupWindow演示应用程序以满足您的需求。 Preview

您可以在其中添加列表或根据需要自定义列表。 的 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();
                }
            }
        });
    }
}

试试这个

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