Question

我希望我的对话框不像所示的图像那样适合整个屏幕。我该如何制作它不会那么长（高度）。

public class SidemenuInfoDialogFragment extends DialogFragment {

      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        RelativeLayout layout = (RelativeLayout) inflater.inflate(R.layout.sidemenu_info_main, container, true);
        return layout;
      }

       @Override
       public Dialog onCreateDialog(Bundle savedInstanceState) {
         Dialog dialog = new Dialog(new ContextThemeWrapper(getActivity(), R.style.Theme_Window_NoMinWith));
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

            return dialog;
          }


}

视图：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:orientation="vertical"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentBottom="true"
                android:id="@+id/sidemenu_info_main_relative">


            <TextView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:id="@+id/text1"
                    android:text="TEST TEXT "/>


</RelativeLayout>

让我知道是否还需要其他东西才能帮助我找到解决问题的正确途径。

Answer 1

将对话框视图高度和宽度内的textview设为“wrap_content”。赞：

<?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:orientation="vertical"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:id="@+id/sidemenu_info_main_relative">

    <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/text1"
            android:text="TEST TEXT "/>

 </RelativeLayout>

Answer 2

尝试更改xml：

<?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:orientation="vertical"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:id="@+id/sidemenu_info_main_relative">


        <TextView
                android:layout_width="100dp"
                android:layout_height="40dp"
                android:id="@+id/text1"
                android:text="TEST TEXT "/>

     </RelativeLayout>

如果这对您不起作用，这是我通常采用的另一种方法：

public class PopUp {
public  void poupUP(final Activity activity) {
    final Dialog dialog = new Dialog(activity, R.style.dialogwithoutTitle);
    dialog.getWindow().setBackgroundDrawable(new      ColorDrawable(android.graphics.Color.TRANSPARENT));
     //here add the layout
    dialog.setContentView(R.layout.pop_up);
   // The comments are to change the position of the alert dialogu
   // WindowManager.LayoutParams wmlp = dialog.getWindow().getAttributes();
    //wmlp.gravity = Gravity.TOP | Gravity.END;
    //wmlp.x = 100;   //x position
    //wmlp.y = 100;   //y position


    dialog.show();
}

}

然后，无论您希望它显示在何处执行此操作：

PopUp p = new PopUp();
p.popUP();

Answer 3

 RelativeLayout layout = (RelativeLayout) inflater.inflate(R.layout.sidemenu_info_main, container, false);

Answer 4

试试这个：

alert.getWindow().setLayout(dialogWidth, LayoutParams.WRAP_CONTENT);
WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
layoutParams.copyFrom(alert.getWindow().getAttributes());
layoutParams.x = xPosition;
layoutParams.y = yPosition;
alert.getWindow().setAttributes(layoutParams);
