打開對話框正好在上下文菜單上單擊項目

Question

我創建了自定義對話框，並希望將其綁定到我的列表項目。 我想要這個對話框長時間點擊列表項時的行爲就像上下文菜單一樣。

換句話說，我不希望這個對話框出現在屏幕的中心，而是出現在列表中的項目附近。

我花了很多時間尋找方式，但不幸的是沒有結果。有一些很好的解決方案嗎？

btn.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 

     // infalte menu 

     PopupMenu popup = new PopupMenu(activity, v); 
     popup.getMenuInflater().inflate(R.menu.clipboard_popup, 
       popup.getMenu()); 
     popup.show(); 
     popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { 
      @Override 
      public boolean onMenuItemClick(MenuItem item) { 

       switch (item.getItemId()) { 
       case R.id.install: 

        // Or Some other code you want to put 
        // here.. This is just an example. 
        Toast.makeText(
          activity, 
          " Install Clicked at position " + " : " 
            + position, Toast.LENGTH_LONG) 
          .show(); 

        break; 
       case R.id.addtowishlist: 

        Toast.makeText(
          activity, 
          "Add to Wish List Clicked at position " 
            + " : " + position, 
          Toast.LENGTH_LONG).show(); 

        break; 

       default: 
        break; 
       } 

       return true; 
      } 
     }); 

    } 
}); 

更新的答案與自定義佈局

PopupWindow popupwindow_obj = popupDisplay(); 
popupwindow_obj.showAsDropDown(clickbtn, -40, 18); 

// where u want show on 
//view click event popupwindow.showAsDropDown(view, x, y); 

    public PopupWindow popupDisplay() 
    { 

     final PopupWindow popupWindow = new PopupWindow(this); 

      // inflate your layout or dynamically add view 
      LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

      View view = inflater.inflate(R.layout.mylayout, null); 

      Button item = (LinearLayout) view.findViewById(R.id.button1); 

      popupWindow.setFocusable(true); 
      popupWindow.setWidth(WindowManager.LayoutParams.WRAP_CONTENT); 
      popupWindow.setHeight(WindowManager.LayoutParams.WRAP_CONTENT); 
      popupWindow.setContentView(view); 

      return popupWindow; 
     } 

mylayout.xml

<LinearLayout 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:orientation="horizontal" > 

     <Button 
      android:id="@+id/button1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="Window test" /> 
    </LinearLayout> 

Answer 2

如果你知道你想你的對話框出現，你可以做這樣的位置（注：X：左 - >右Y：頂部 - >底部）

AlertDialog dialog = builder.create(); 
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    WindowManager.LayoutParams abc= dialog.getWindow().getAttributes(); 

abc.gravity = Gravity.TOP | Gravity.LEFT; 
abc.x = 100; //x position 
abc.y = 100; //y position 

dialog.show();
