這與我的previous question類似,但它不適用於Kindle Fire(2.3.4)。
我使用FragmentTransaction將一個片段添加到FrameLayout中。我想動態地改變片段使用的RelativeLayout的邊距。在RelativeLayout上設置頁邊距在Kindle Fire上不起作用
但是,Kindle Fire上的FrameLayout.layoutParams的邊距沒有變化。但是,這適用於3.2.1。我也嘗試使用setMargins(),它沒有工作。
有誰知道我如何動態地改變Kindle Fire的邊距?
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.infocard, container, false);
RelativeLayout infoLayout = (RelativeLayout) view.findViewById(R.id.info);
infoLayout.setOnClickListener(new EmptyClickListener());
final int width = 250;
final int height = 270;
int leftMargin = 0;
int topMargin = 0;
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(width, height);
if (x - width < 0) {
leftMargin = 0;
} else {
leftMargin = x - width + 40;
}
if (y >= 400 && y <= 480) {
topMargin = 160;
}
params.leftMargin = leftMargin;
params.topMargin = topMargin;
//params.setMargins(leftMargin, topMargin, 0, 0); //this didnt work either
infoLayout.setLayoutParams(params);
TextView titleView = (TextView) view.findViewById(R.id.titleCard);
titleView.setText(title);
return view;
}
是infoLayout一個FrameLayout裏或RelativeLayout的的子視圖? – 2012-03-22 00:04:59
infoLayout是一個RelativeLayout – heero 2012-03-22 00:08:25
爲什麼使用FrameLayout.LayoutParams代替RelativeLayout.LayoutParams?你有沒有嘗試過使用RelativeLayout.LayoutParams?更重要的是,你有沒有嘗試調用params = infoLayout.getParams();然後編輯參數而不是重新創建它們? – 2012-03-22 00:15:57
