【问题描述】：

我正在尝试让锻炼列表页面上的耐力按钮启动耐力列表。热身按钮工作正常。但是，耐力按钮在单击时会使应用程序崩溃。这是 Java 练习列表：

    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;  
        }

    }




}

以下是按下按钮时出现的错误：

请帮我解决这些问题。我是全新的！

【问题讨论】：

正如 exeption 所说，“没有找到处理 Intent 的活动 {act=com.example.chopbuilderfordrums.LaunchEnduranceList” - 您的项目中是否有 LaunchEnduranceList.java 扩展了 Activity 或其子类之一?这有什么奇怪的依赖关系吗？你的 proguard 是否配置错误？
您在manifest.xml 中是否正确定义了LaunchEnduranceList？试试startActivity(new Intent(ExerciseList.this, LaunchEnduranceList.class));
我确实有一个 LaunchEnduranceList.java。这是那个：
您不需要发布该课程
就是这样！！谢谢。我的清单中没有正确说明。我需要补充：

标签： java android android-intent

【解决方案1】：

你确定从这个

com.example.chopbuilderfordrums.LaunchEnduranceList

试试这个，如果它给你同样的异常，那意味着你没有活动类

startActivity(new Intent(this, LaunchEnduranceList.Class));

【解决方案2】：

据此：

android.content.ActivityNotFoundException:
     No Activity found to handle Intent 
    { act=com.example.chopbuilderfordrums.LaunchEnduranceList }

com.example.chopbuilderfordrums.LaunchEnduranceList Activity 是：

未在 AndroidManifest.xml 中声明
您还没有创建LaunchEnduranceList 类： public class LaunchEnduranceList extends Activity
