缩小屏幕上的对话框

Question

我希望我的对话框不像显示的图像那样适合整个屏幕。我应该怎么做才不会那么长（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来帮助我走上正确的道路来解决这个问题。

Answer 1

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

Answer 2

试着改变你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();
}

}

然后在任何您想显示的地方执行此操作：

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

在对话框视图中将文本视图的高度和宽度设置为 "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 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);
