我对 ListView
有点意见。在知道 ListView
内容有自定义适配器的情况下,如何清除该内容?

自定义适配器类扩展了 BaseAdapter
,它看起来像这样:
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
public class MyAdapter extends BaseAdapter {
private Activity activity;
private String[] data;
private static LayoutInflater inflater = null;
public MyAdapter(Activity a, String[] str) {
activity = a;
data = str;
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public static class ViewHolder {
public TextView text;
}
@Override
public int getCount() {
return data.length;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View view, ViewGroup parent) {
View v = view;
ViewHolder holder;
if (v == null) {
v = inflater.inflate(R.layout.rowa, null);
holder = new ViewHolder();
holder.text= v.findViewById(R.id.dexter);
v.setTag(holder);
} else {
holder = v.getTag();
}
holder.text.setText(data[position]);
return v;
}
}
