在我使用我的按钮访问我的列表视图后，在关注代码并显示没有错误后，强制关闭我的代码如下

import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class Listview extends ListActivity {

String classNames[] = {"home1", "Sweet", "tutorial2"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setListAdapter(new ArrayAdapter<String>(this,   android.R.layout.simple_list_item_1, classNames));

}@Override
protected void onListItemClick (ListView lv, View v, int position, long id){
    super.onListItemClick(lv, v, position, id);
    String openClass = classNames[position];
    try{
        Class selected = Class.forName("us.beats.with." + openClass);
        Intent selectedIntent = new Intent(this, selected);
        startActivity(selectedIntent);
    }catch (ClassNotFoundException e){
        e.printStackTrace();

Answer 1

按钮设置的地方我有Button Listview =（Button）findViewById（R.id.Listview）; Listview.setOnClickListener（new View.OnClickListener（）{

        public void onClick(View v) {
            // TODO Auto-generated method stub
        startActivity(new Intent("us.beats.with.Mylist"));
        mpButtonClick.start();

但是启动活动是us.beats.with.Listview应该是上面的

    public class MyList extends ListActivity {

String classNames[] = {"home1", "Sweet", "tutorial2"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setListAdapter(new ArrayAdapter<String>(this,   android.R.layout.simple_list_item_1, classNames));

}@Override
protected void onListItemClick (ListView lv, View v, int position, long id){
    super.onListItemClick(lv, v, position, id);
    String openClass = classNames[position];
    try{
        Class selected = Class.forName("us.beats.with." + openClass);
        Intent selectedIntent = new Intent(this, selected);
        startActivity(selectedIntent);
    }catch (ClassNotFoundException e){
        e.printStackTrace();
    }
}

现在运行上面的代码
