我的Android应用程序保持关闭

Question

我不明白为什么当我在模拟器中运行它时，它强制关闭。我做了一个闪屏，并且出现没有问题，但它不会通过了：

启动画面后

public class MainActivity extends Activity 
{ 
protected boolean _active = true; 
protected int _splashTime = 5000; 

// Called when the activity is first created. 
@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    // thread for displaying the SplashScreen 
    Thread splashTread = new Thread() 
    { 
     @Override 
     public void run() 
     { 
      try 
      { 
       int waited = 0; 
       while(_active && (waited < _splashTime)) 
       { 
        sleep(100); 
        if(_active) 
        { 
         waited += 100; 
        } 
       } 
      } 
      catch(InterruptedException e) 
      { 
       // do nothing 
      } 
      finally 
      { 
       finish(); 
       startActivity(new Intent("com.example.textsmslock.EnableActivity")); 
       stop(); 
      } 
     } 
    }; 
    splashTread.start(); 
} 

@Override 
public boolean onTouchEvent(MotionEvent event) { 
    if (event.getAction() == MotionEvent.ACTION_DOWN) { 
     _active = false; 
    } 
    return true; 
} 
} 

，它应该是去下面的另一个活动代码：

public class Enable extends Activity { 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_enable); 
    // getActionBar().setDisplayHomeAsUpEnabled(true); 
} 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.activity_enable, menu); 
    return true; 
} 


@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
     case android.R.id.home: 
      NavUtils.navigateUpFromSameTask(this); 
      return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 
public void EnableYes(View view) 
{ 
    startActivity(new Intent("com.example.textsmslock.EnterPin")); 
} 
public void EnableNo(View view) 
{ 

} 

}

Answer 1

我错过了我的清单

<intent-filter> 
      <action android:name="com.example.textsmslock.Enable" /> 
      <category android:name="android.intent.category.DEFAULT" /> 
     </intent-filter> 

Answer 2

没有一个堆栈跟踪其很难说，但最有可能的是没有活动称为EnableActivity。根据您的代码，该活动被称为Enable。

类型安全的方式做到这一点，是不使用字符串，而是startActivity(new Intent(this, com.example.textsmslock.Enable.class))

Answer 3

首先，我认为你开始第二Activity错误。在你MainActivity，你有这样的：

startActivity(new Intent("com.example.textsmslock.EnableActivity")); 

当你应该有这样的事情：

startActivity(new Intent(this, Enable.class)); 

其次，这是多么Enable可能看起来像在您的清单。你真的没有指示与meta-data标签父活动：

<activity android:name="com.example.textsmslock.Enable" 
    android:label="@string/title_activity_enable"></activity> 

第三，当人们说“堆栈跟踪，”你通常看到在logcat的红色打印出来。这意味着有一个Exception或抛出一个错误。
