添加你的代碼，你已經嘗試 –

'AndroidRuntimeException此錯誤：從外部調用startActivity（）活動上下文 - 搜索這個錯誤，你會得到http://stackoverflow.com/questions/3689581/calling-startactivity-from-outside-of-an-activity – PPartisan

使用此：

button.setOnClickListener(new View.OnClickListener() 
    { 
      public void onClick(View v) { 
      Intent i = new Intent(PresentActivity.this,NextActivity.class); 
      i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
      startActivity(i); 
     } 
    });
