DialogFragment 自定义布局全屏的正确姿势

public class FullscreenDialog extends CommonDialog {

    @Override
    public void onResume() {
        super.onResume();
        Window mWindow = getDialog().getWindow();
        WindowManager.LayoutParams mLayoutParams = mWindow.getAttributes();
        mLayoutParams.width = ViewGroup.LayoutParams.MATCH_PARENT;
        mLayoutParams.height = ViewGroup.LayoutParams.MATCH_PARENT;
        mLayoutParams.gravity = Gravity.CENTER;
        mWindow.setAttributes(mLayoutParams);
    }
}
