Android中dialog实现横竖屏切换适配效果

@Override
public void onContentChanged() {
    super.onContentChanged();
    // 解决横竖屏切换的适配问题
    Display display = mActivity.getWindowManager().getDefaultDisplay();
    WindowManager.LayoutParams params = this.getWindow().getAttributes();
    params.width = display.getWidth();
    this.getWindow().setAttributes(params);
    this.getWindow().setGravity(Gravity.BOTTOM);
}
