我试图将图像添加到我的ListView,使它看起来更像一个按钮。我想图像要小一点,也许60%的电流。并且图像很好地LIGN向上的右侧一列。这里是什么,我现在有一个画面:
I am trying to add an image to my ListView to make it look more like a button. I would like the images to be a little smaller, maybe 60% of current. And the images to lign up nicely on the right in a column. Here is a screen of what I currently have:
和这里是我的列表视图中的xml:
and here is my list view xml:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="16sp"
android:layout_width="match_parent"
android:drawableRight="@drawable/arrow_button"
>
</TextView>
任何想法,我在做什么错误?
any idea what I am doing incorrectly?
这包含此TextView的ListView控件的定义是这样的:
The ListView that contains this TextView is defined like this:
一注,该方式创建和我列出的工作是与ListAdapter,用code是这样的:
One note, the way I create and work with my Lists is with the ListAdapter, using code like this:
Question q = new Question ();
q.setQuestion( "This is a test question and there are more than one" );
questions.add(q);
adapter = new ArrayAdapter<Question>( this, R.layout.questions_list, questions);
setListAdapter(adapter);
谢谢!
推荐答案
通过评论和建议弗兰克Sposaro了,你就可以正确地定位你的看法。
With the comment and advice that Frank Sposaro gave, you will be able to position your views correctly.
有关你的下一个问题,我建议你做你自己的适配器与此类似:
For your next problem, I advice you to make your own adapter similar to this:
private class CustomAdapter extends ArrayAdapter<Question> {
private LayoutInflater mInflater;
public CustomAdapter(Context context) {
super(context, R.layout.row);
mInflater = LayoutInflater.from(context);
}
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.row, null);
holder = new ViewHolder();
holder.text = (TextView) convertView.findViewById(R.id.mTextView);
holder.image = (ImageView) convertView.findViewById(R.id.mImage);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
//Fill the views in your row
holder.text.setText(questions.get(position).getText());
holder.image.setBackground... (questions.get(position).getImage()));
return convertView;
}
}
static class ViewHolder {
TextView text;
ImageView image;
}
在您的onCreate:
In your onCreate:
ListView mListView = (ListView) findViewById(R.id.mListView);
mListView.setAdapter(new CustomAdapter(getApplicationContext(), questions));
这里
再比如用于与适配器一个ListView可以发现
