DialogFragment使用笔记

1. DialogFragment默认边框有黑色阴影

2. 去掉黑色阴影

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setStyle(STYLE_NORMAL, R.style.Theme_Common_Dialog_Alert);
}

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.Common.Dialog.Alert" parent="android:Theme.Panel">
    	<!-- 让Dialog背景为灰色，默认false是背景高亮 -->	
        <item name="android:backgroundDimEnabled">true</item>
    </style>
</resources> 

3. 设置Dialog固定宽高,在xml中设置是无效的

@Override
public void onResume() {
    super.onResume();
    if (getShowsDialog()) {
        //Dialog显示时，设置Dialog的固定宽度。
        getDialog().getWindow().setLayout(getActivity().getResources().getDimensionPixelSize(R.dimen.dialog_min_width), LinearLayout.LayoutParams.WRAP_CONTENT);
    }
}

4. 设置Dialog无标题，点击外部是否消失

  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
      if (getShowsDialog()) {
          getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
          getDialog().setCanceledOnTouchOutside(false);
      }
	
//....
  }
