如何在Android中从右侧动态添加View?
我需要在 Android 的 Fragment 中从右侧布局视图,但是,android 并没有按照我的想法布局子视图。 我尝试将TableLayout和ImageView添加到LINEARLAYOUT,ImageView的宽度是固定的,TableLayout的宽度是动态的。此外,ImageView 需要位于右侧。 部分源代码:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
Context c = getActivity().getApplicationContext();
LinearLayout l = new LinearLayout(c);
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT, 0);
params.gravity = Gravity.RIGHT;
l.setLayoutParams(params);
// l.setGravity(Gravity.RIGHT);
PankouAttachmentView pav = new PankouAttachmentView(c, null);
pav.setLayoutParams(params);
l.addView(pav);
ImageView iv = new ImageView(c);
iv.setClickable(true);
iv.setFocusable(true);
iv.setImageResource(R.drawable.testarrow);
iv.setMaxWidth(BUTTON_WIDTH);
iv.setLayoutParams(new LayoutParams(BUTTON_WIDTH,
LayoutParams.MATCH_PARENT));
l.addView(iv);
return l;
}
任何帮助将不胜感激。THX:)
I need to layout the views from the RIGHT side in a Fragment in Android, however, android did not layout the sub views as what I thought.
I tried to add a TableLayout and an ImageView to a LINEARLAYOUT, the width of the ImageView was fixed and the width of TableLayout is dynamic. Furthermore, the ImageView need to be located on the right side.
Part of the source code:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
Context c = getActivity().getApplicationContext();
LinearLayout l = new LinearLayout(c);
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT, 0);
params.gravity = Gravity.RIGHT;
l.setLayoutParams(params);
// l.setGravity(Gravity.RIGHT);
PankouAttachmentView pav = new PankouAttachmentView(c, null);
pav.setLayoutParams(params);
l.addView(pav);
ImageView iv = new ImageView(c);
iv.setClickable(true);
iv.setFocusable(true);
iv.setImageResource(R.drawable.testarrow);
iv.setMaxWidth(BUTTON_WIDTH);
iv.setLayoutParams(new LayoutParams(BUTTON_WIDTH,
LayoutParams.MATCH_PARENT));
l.addView(iv);
return l;
}
Any help will be appreciated.THX :)

我不确定我完全理解你的问题,但你尝试过使用相对布局吗?相对布局比线性布局更容易完成。请参阅 android hello 视图 教程。
I'm not sure I completely understand your question but have you tried using a relative layout? Relative layout lets you accomplish much easier than a linear layout. See the android hello views tutorial.
