如何获取android中自定义对话框的大小？ [英] How to get size of a custom dialog in android?

问题描述

我有一个从对话框扩展的自定义对话框。
为了放置组件，我需要知道对话框的宽度。我该怎么办？
谢谢

编辑：

  public class AnswerTypeDialog extends Dialog {
 public AnswerTypeDialog（Context context）{
 super（context）; 
 mContext = context; 
} 
 
 @Override 
 protected void onCreate（final Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 init（）; 
} 
 
 protected void init（）{
 ll =（RelativeLayout）LayoutInflater.from（mContext）.inflate（R.layout.answertype_layout，null）; 
 this.requestWindowFeature（Window.FEATURE_NO_TITLE）; 
 setContentView（ll）; 
 mWindowWidth = this.getWindow（）。getAttributes（）。width; 
} 
} 
  

mWindowWidth为零

解决方案

这将工作。

  @Override 
 public void onWindowFocusChanged（boolean hasFocus）{
 super.onWindowFocusChanged（hasFocus）; 
 int height = mDialog.getWindow（）。getDecorView（）。getHeight（）; 
 int width = mDialog.getWindow（）。getDecorView（）。getWidth（）; 
} 
  

I have a custom Dialog which is extended from dialog. in order to place component on it, I need to know the width of the dialog. how could I do it? Thanks

EDIT:

public class AnswerTypeDialog extends Dialog{
    public AnswerTypeDialog(Context context) {
        super(context);
        mContext = context;
    }

    @Override
    protected void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        init();
    }

    protected void init(){
        ll=(RelativeLayout) LayoutInflater.from(mContext).inflate(R.layout.answertype_layout, null);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(ll);
        mWindowWidth = this.getWindow().getAttributes().width;
    }
}

mWindowWidth is zero.

解决方案

This will work.

@Override
    public void onWindowFocusChanged (boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        int height=mDialog.getWindow().getDecorView().getHeight();
    int width=mDialog.getWindow().getDecorView().getWidth();
}
