Question

在android中用一个activity 调用另一个activity，结果按下第一个activity的按钮后，就出现错误，

package stella.activity;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class Activity02Activity 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.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(Activity02Activity.this, OtherActivity.class);
Activity02Activity.this.startActivity(intent);
}
}
}
ps,第二个activity已在manifest那里注册了

Answer 1

myButton.setOnClickListener(listener2);

private Button.OnClickListener listener2=new Button.OnClickListener(){

public void onClick(View v) {
Intent i=new Intent();
i.setClass(Activity02Activity.this, OtherActivity.class);
startActivity(i);
}};
你这样试试
或者myButton.setOnClickListener(new MyButtonListener());改为myButton.setOnClickListener(new MyButtonListener(this));

Answer 2

这应该不是第一个Activity的配置的问题，而是你第二个activity代码是否正确。看看第二个Activity继续Activity没。

Answer 3

额，你把错误的Log贴出来撒，这么看貌似没错啊。。。

Answer 4
