我正在尝试使“锻炼列表”页面上的“耐力”按钮启动“耐力”列表。 “热身”按钮可以正常工作。但是，耐用性按钮会使应用程序在单击时崩溃。这是练习列表Java：
package com.example.chopbuilderfordrums;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class ExerciseList extends Activity implements View.OnClickListener {
Button button1;
Button button2;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_exercise_list);
button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(this);
button2 = (Button)findViewById(R.id.button2);
button2.setOnClickListener(this);
}
private void button1Click()
{
startActivity(new Intent("com.example.chopbuilderfordrums.LaunchWarmupsList" ));
}
private void button2Click()
{
startActivity(new Intent("com.example.chopbuilderfordrums.LaunchEnduranceList" ));
}
public void onClick (View v) {
switch (v.getId())
{
case R.id.button1:
button1Click();
break;
case R.id.button2:
button2Click();
break;
}
}
}
这是按下按钮时出现的错误：
