android - 当我调用 Activity 启动器方法时，应用程序随机崩溃

Question

当按下调用跟随监听器的两个按钮之一时

OnClickListener mSportiveListener = new OnClickListener() {
    public void onClick(View v) {
        String title = getResources().getString(
                R.string.function_sport_i);
        String category="SPORT";
        startFunctionSelector(title, category);
    }
};

OnClickListener mClassicListener = new OnClickListener() {
    public void onClick(View v) {
        String title = getResources().getString(
                R.string.function_classic_i);
        String category="CLASSIC";
        startFunctionSelector(title, category);
    }
};

应用程序经常崩溃，并提供有关在线发生的错误的任何详细信息

startActivity(selector);

方法

public void startFunctionSelector(String title, String functionCategory) {
    Intent selector = new Intent(Home.this, FunctionSelector.class);
    selector.putExtra("Title", title);
    selector.putExtra("FunctionCategory", functionCategory);
    try {
        startActivity(selector);
    } catch (RuntimeException e) {
        e.printStackTrace();
    }

}

该错误与FunctionSelector.class无关，因为无论我输入什么内容，其行为都是完全相同的(我也尝试过使用Hello World)

不幸的是，由于某些奇怪的原因，Eclipse 没有给我有关该错误的任何详细信息，只有一个通用的 SourceNotFound与

// Compiled from Handler.java (version 1.5 : 49.0, super bit)
public class android.os.Handler {

  // Method descriptor #11 ()V
  // Stack: 3, Locals: 1
  public Handler();
     0  aload_0 [this]
     1  invokespecial java.lang.Object() [1]
     4  new java.lang.RuntimeException [2]
     7  dup

      Local variable table:
        [pc: 0, pc: 14] local: this index: 0 type: android.os.Handler

但没有具体说明该问题。

更多详细信息

FunctionSelector 的 onCreate，但正如我所说，如果我在此 Activity 中仅留下 helloWorld，也会崩溃

 public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
                    .permitAll().build();
            StrictMode.setThreadPolicy(policy);
            setContentView(R.layout.selector_gui);

            selectorTitle = getIntent().getStringExtra("Title");
            functionCategory = getIntent().getStringExtra("FunctionCategory");

            buttonBack = (ImageButton) findViewById(R.id.btBack);
            buttonBack.setOnClickListener(mBackListener);

            txtTitle = (TextView) findViewById(R.id.txtTitle);
            txtTitle.setText(selectorTitle);

            list = (ListView) findViewById(R.id.listaFunzioni);

        }

如果我尝试使用模拟器并进入 AllMessage(每个应用程序未过滤)，我可以看到

Answer 1

尝试这些步骤

1) 例如，在初始化 Intent 时尝试包含 Activity 的完整路径

Intent selector = new Intent(Home.this, com.yourpackagename.YourActivity.class); 

list 中的 Activity 声明中的内容相同

2) 验证所有资源是否正确链接，并且 list 和 gui 的 xml 文件中没有错误

3) 假设您已在 list 中声明了该 Activity，并且 on create 中的资源已正确初始化。 Eclipse 缓存中可能出现问题，删除工作区中的 .metadata 文件夹并尝试重新导入项目。
