Android的，不能讓基法setOnLongClickListener工作

Question

我試圖檢測長按並獲得

The methed 'setOnLongClickListener' in type view is not applicable for the argument 'new OnLongClickListener()'

的代碼看起來像

t.setOnLongClickListener(new OnLongClickListener() { 
    @Override 
    public boolean onLongClick(View v) { 
     //Offer additional options when the view is held. 
      MakeRingtune(strLastSound); 
     return true; 
    } 
}); 

Answer 1

有多種內部類名爲OnLongClickListener在android API中：View.OnLongClickListener和AdapterView.OnLongClickListener。

因此請檢查您的導入聲明並確保您使用正確的導入聲明。

Answer 2

嘗試下面：

t1.setOnLongClickListener(new View.OnLongClickListener() { <--- check here. 
    @Override 
    public boolean onLongClick(View v) { 
     // TODO Auto-generated method stub 
     Toast.makeText(getBaseContext(), "Long Clicked", Toast.LENGTH_SHORT).show(); 
     return true; 
    } 
});
