.setPositiveButton("关闭", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
}
}).create();
alertDialog.show();

@Override
public void setInfo(String nm, int position) {
alertDialog.dismiss();
Toast.makeText(MainActivity.this, "测试代码", Toast.LENGTH_SHORT).show();
}
});
}
自定义listview的适配器代码
public class MyAdapter extends BaseAdapter {
private LayoutInflater mInflater;
OnCall onCall;
List<String> mDatas ;
public MyAdapter(Context context, List<String> list) {
this.mInflater = LayoutInflater.from(context);
mDatas = list ;
}
public void setOnCall(OnCall onCall) {
this.onCall = onCall;
}
@Override
public int getCount() {
return mDatas.size();
}
@Override
public Object getItem(int position) {
return mDatas.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
// Item View的复用
if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.my_listview_item, null);
// 获取title
holder.textView = (TextView)convertView.findViewById(R.id.textview);
convertView.setTag(holder);
} else {
holder = (ViewHolder)convertView.getTag();
}
holder.textView.setText(mDatas.get(position));
holder.textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
onCall.setInfo(mDatas.get(position),position);
}
});
return convertView;
}
private class ViewHolder {
private TextView textView;
}
public interface OnCall {
public void setInfo(String nm, int position);
}
}
layout_test布局代码
<ListView
android:id="@+id/listview"
android:layout_marginTop="20dp"
android:layout_width="match_parent"
android:layout_height="300dp"
/>
子布局代码
<androidx.appcompat.widget.AppCompatTextView
android:layout_width="match_parent"
