我正在尝试创建一个采用“发布”形式的viewGroup,我需要此视图在左上角有一个图像,然后是该帖子右侧的用户名和内容,与彼此对齐,但我似乎无法让布局移动。他们只是保持重叠。Android RelativeLayout不移动项目
public ViewGroup generateViewGroup(Context context){
RelativeLayout rl = new RelativeLayout(context);
WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
Point p = new Point();
wm.getDefaultDisplay().getSize(p);
TextView tvUsername = new TextView(context);
tvUsername.setText(userName);
TextView tvPostContent = new TextView(context);
tvPostContent.setText(postContent);
ImageView iv = new ImageView(context);
RelativeLayout.LayoutParams lpTvUsername = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
lpTvUsername.addRule(RelativeLayout.RIGHT_OF,0);
lpTvUsername.addRule(RelativeLayout.ALIGN_TOP,0);
tvUsername.setLayoutParams(lpTvUsername);
RelativeLayout.LayoutParams lpTvPostContent = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
lpTvPostContent.addRule(RelativeLayout.RIGHT_OF,0);
lpTvPostContent.addRule(RelativeLayout.BELOW,1);
tvPostContent.setLayoutParams(lpTvPostContent);
LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
if (userPic==null) Log.e("generateViewGroup","userPic is null");
iv.setImageDrawable(userPic);
rl.addView(iv, 0);
rl.addView(tvUsername,1);
rl.addView(tvPostContent);
rl.setLayoutParams(lp);
}
您不想夸大XML的具体原因是什么? – Droidekas 2015-03-03 05:46:49
我想坚持java,因为我们有许多其他类与这一个(http请求等)一起工作,所以它不会很容易在XML中做 – 2015-03-03 06:40:30
