两个Activity之间切换的有关问题

两个Activity之间切换的问题。

第一个Activity

Java code

package richy.activity;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.Button;public class Activity_02Activity extends Activity {    /** Called when the activity is first created. */    private Button myButton = null;    @Override       public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        myButton = (Button)findViewById(R.id.myButton);        myButton.setText("第二个Activity");        myButton.setOnClickListener(new MyButtonListener());    }        class MyButtonListener implements android.view.View.OnClickListener{        @Override        public void onClick(View v) {            // TODO Auto-generated method stub            Intent intent = new Intent();            intent.setClass(Activity_02Activity.this, OtherActivity.class);            Activity_02Activity.this.startActivity(intent);        }            }}

第二个Activity

Java code

package richy.activity;import android.app.Activity;import android.os.Bundle;import android.widget.TextView;public class OtherActivity extends Activity{    private TextView myTextView = null;    @Override    protected void onCreate(Bundle savedInstanceState) {        // TODO Auto-generated method stub        super.onCreate(savedInstanceState);        setContentView(R.string.other);        myTextView = (TextView)findViewById(R.id.mytextView);        myTextView.setText(R.string.app_name);    }}

在AndroidManifest.xml中已经注册了第二个Activity。
点击Button之后，程序就错误停止了。

[解决办法]
R.string.other是什么东东
[解决办法]
class MyButtonListener implements android.view.View.OnClickListener{
换成
private final Button.OnClickListener MyButtonListener = new Button.OnClickListener() {
