StartActivity가 ListView.setOnItemClickListener에서 충돌합니다.

Question

활동 시작에 이상한 점이 있습니다. 나는

Intent intent = new Intent(this,SplashScreen.class); 
this.startActivity(intent); 

를 사용하여 메뉴에서 시작할 수 있어요하지만 난 ListView.setOnItemClickListener에서 시작하려고하면, 그것은 충돌합니다. 그러나 나는 모든 종류의 메소드를 시도했는데, 결과는 동일합니다 (시작하려는 작업은 빈 화면이므로 아무 것도 의심스럽지 않습니다). 여기

 list.setOnItemClickListener(new OnItemClickListener() { 
      public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) { 
startActivity(new Intent(getBaseContext(), SplashScreen.class)); 
      }});  

활동은 매니페스트에 추가됩니다 ... 그리고 메인 클래스 활동을 확장 ... 현재 코드입니다.

당신이 getBaseContext()이 함께 활동 이름을 사용하지 않아도

.

list.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
    startActivity(new Intent(YourActivityName.this, SplashScreen.class)); 
    } 
}); 

확인 매니페스트에서 모두 활동 :

<application ...> 
    <activity android:name="your.package.name.MainActivity" /> <!-- or .MainActivity --> 
    <activity android:name="your.package.name.SplashScreen" /> 
</application>
