我很难让LayoutInflater按预期工作,其他人也是如此:如何使用layoutinflator在运行时添加视图？.
为什么LayoutInflater会忽略我指定的布局参数？例如,为什么我的资源XML中的值layout_width和layout_height值不受尊重？
Avoid passing null as the view root当用nullas 膨胀视图时,我得到了lint警告parent,例如:
LayoutInflater.from(context).inflate(R.layout.dialog_edit, null);
但是,视图是用作一个内容AlertDialog,使用setViewon AlertDialog.Builder,所以我不知道应该传递什么parent.
parent在这种情况下你认为应该是什么？
当我使用弹出窗口显示时,我希望能够模糊或调暗背景popup.showAtLocation,并在popup.dismiss调用时将背景解开/调暗.
我曾尝试应用布局PARAMS FLAG_BLUR_BEHIND和FLAG_DIM_BEHIND我的活动,但这似乎只是一旦我的应用程序开始模糊和朦胧的背景.
如何使用弹出框进行模糊/调光？
我想写一个ListView基本格式,但我收到一个错误:
UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView
和:
androidview.LayoutInfalater.inflate(LayoutInflater.java: some numbers....like 720,658...so on)
我知道应该在适配器类中完成一些事情:
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
RelativeLayout rv = new RelativeLayout(c);
TextView tv = new TextView(c);
TextView tv1 = new TextView(c);
ImageView imgv = new ImageView(c);
tv.setText(s[position]);
tv1.setText(i[position]);
imgv.setImageResource(d[position]);
rv.addView(tv);
rv.addView(tv1);
rv.addView(imgv);
return rv;
}
我该怎么做才能解决问题
