Question

我想将对话框的位置设置在点击它的同一位置..就像这样

但我得到了这个

这是我的位置对话框的代码..

    public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
        float positionX = v.getX();
        float positionY = v.getY();

        LinearLayout container = (LinearLayout) gvGrid.getFocusedChild();

        dialog = new Dialog(CW_Emergency.this);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.view_pager_layout);
        dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

        //position of popup
        WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
        params.x = (int) positionX;
        params.y = (int) positionY;

        ViewPagerAdapter adapter = new ViewPagerAdapter(container, CW_Emergency.this);
        viewPager = (ViewPager) dialog.findViewById(R.id.view_pager);

        dialog.show();



    }

请告诉我如何针对所有屏幕尺寸正确定位

Answer 1

您可以使用PopupWindow。

 mPopupWindow = new PopupWindow(
                    customView,
                    LayoutParams.WRAP_CONTENT,
                    LayoutParams.WRAP_CONTENT
            );

并显示

mPopupWindow.showAsDropDown(ItemInGridView, 0, -1 * ItemInGridView.getHeight(), Gravity.LEFT);

根据我在正确位置显示对话框 PopupMenu 会更方便和简单。实现PopupMenu ......

首先，您必须在菜单资源文件夹

中创建菜单资源文件

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/menu_option1"
  android:title="Option 1"
  />
<item android:id="@+id/menu_option2"
  android:title="Option 2"
  />
</menu>

在 onItemClick（）方法中实现以下代码

public void onItemClick(AdapterView<?> parent, View v, int position, long id) {

PopupMenu popup = new PopupMenu(this, v);
// Inflate the menu from xml
popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu());
// Setup menu item selection
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
    public boolean onMenuItemClick(MenuItem item) {
        switch (item.getItemId()) {
        case R.id.menu_option1:
            Toast.makeText(MainActivity.this, "Option 1", Toast.LENGTH_SHORT).show();
            return true;
        case R.id.menu_option2:
            Toast.makeText(MainActivity.this, "Option 2", Toast.LENGTH_SHORT).show();
            return true;
        default:
            return false;
        }
    }
});
// Show the menu
popup.show();

 }

PopupMenu将准确显示在您要点击的视图附近。
