package com.example.listview;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
public class MainActivity extends ListActivity {
private TextView textView;
private ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView)findViewById(R.id.text);
listView = getListView();//getListView()是ListActivity中的方法,返回一个ListView
listView.setTextFilterEnabled(true);
ArrayAdapter<CharSequence> adap = ArrayAdapter.createFromResource(this, R.array.weekday, android.R.layout.simple_list_item_1);
setListAdapter(adap);
AdapterView.OnItemClickListener listener = new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
textView.setText(((TextView)view).getText());//设置用户单击的项目的文字显示在textView上
}
};
listView.setOnItemClickListener(listener);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
结果一运行,就自动退出了,不知道哪里出错了,还请各位帮帮忙,谢谢了
