我正在使用此代码搜索List并将它们添加到List(s是EditText):
if (s != null && s.toString().length() > 2) {
SearchDialogList.clear();
for (String tmp : mSuraNameList)
if (tmp.startsWith(s.getText().toString()))
SearchDialogList.add(tmp);
if (SearchDialogList.size() != 0) {
mSearchDialogAdapter = new ListView_StartQuranSearchDialog_Adapter(Start_Quran_List2.this, SearchDialogList);
listview.setAdapter(mSearchDialogAdapter);
}
}
适配器GetView():
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.readers_choice_custom_row, null); // line
// 47
holder = new ViewHolder();
holder.tv_ReadersNames = (TextView) convertView.findViewById(R.id.TextView_ReaderChoiceDownload);
convertView.setTag(holder);
} else
holder = (ViewHolder) convertView.getTag();
holder.tv_ReadersNames.setText(SuraList.get(position));
holder.tv_ReadersNames.setGravity(Gravity.RIGHT);
return convertView;
}
class ViewHolder {
TextView tv_ReadersNames;
}
xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="15dip">
<TextView
android:id="@+id/TextView_ReaderChoiceDownload"
android:textAppearance="?android:attr/textAppearanceLarge"
android:layout_height="wrap_content"
android:text="tes"
android:layout_width="wrap_content"
android:layout_alignParentRight="true"
android:padding="15dip"></TextView>
/>
列表不为空,为什么ListView不显示列表中的项目?

使用s.toString()
s.getText().toString()
