我有一個應用程序,當我們點擊一​​個按鈕的應用程序啓動谷歌地圖與搜索查詢。但我需要打開該位置才能提供準確的結果。可能嗎?如何提示用戶打開位置?

您應該在您的AndroidManifest.xml中添加permission

有關Android權限的一般信息here

請注意Android 6權限機制已更改(it became iOS like)。

我明白您的查詢 這裏是應該在你的onCreate方法可以添加代碼

LocationManager lm = (LocationManager) getSystemService(LOCATION_SERVICE); 
    if (!lm.isProviderEnabled(LocationManager.GPS_PROVIDER) || 
      !lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) { 
     // Build the alert dialog 
     AlertDialog.Builder builder = new AlertDialog.Builder(this); 
     builder.setTitle("Location Services Not Active"); 
     builder.setMessage("Please enable Location Services and GPS"); 
     builder.setPositiveButton("OK", new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialogInterface, int i) { 
       // Show location settings when the user acknowledges the alert dialog 
       Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); 
       startActivity(intent); 
      } 
     }); 
     Dialog alertDialog = builder.create(); 
     alertDialog.setCanceledOnTouchOutside(false); 
     alertDialog.show(); 
    }
