在請求運行時權限時關閉應用程序

Question

在詢問用戶運行時權限的同時，獲取以下覆蓋對話框。

下面是我的代碼：

if(ContextCompat.checkSelfPermission(MainActivity.this,permissions) == PackageManager.PERMISSION_DENIED) { 
     if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, permissions)) { 
      ActivityCompat.requestPermissions(MainActivity.this,new String[] {permissions}, requestCode); 
     } else 
      Toast.makeText(MainActivity.this,"Need Permission",Toast.LENGTH_LONG); 
    } 

清單

<uses-permission android:name="android.permission.CALL_PHONE" /> 

許可，我請求是CALL_PHONE。

TIA

也許您沒有爲AndroidManifest添加描邊？ 我的確如下： 添加了對AndroidManifest的筆劃

然後檢查程序的運行時權限。

MainActivity： verifyStoragePermissions（this）;

public static void verifyStoragePermissions(Activity activity) { 
    // Check if we have write permission 
    int permission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE); 
    if (permission != PackageManager.PERMISSION_GRANTED) { 
     // We don't have permission so prompt the user 
     if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE)) { 
     } else { 
      ActivityCompat.requestPermissions(activity, PERMISSIONS_STORAGE, REQUEST_EXTERNAL_STORAGE); 
     } 
    } 
} 

然後檢查結果MainActivity：

@Override 
public void onRequestPermissionsResult(int requestCode, 
             String permissions[], int[] grantResults) { 
    switch (requestCode) { 
     case Utils.REQUEST_EXTERNAL_STORAGE: { 
      // If request is cancelled, the result arrays are empty. 
      if (grantResults.length > 0 
        && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
       // permission was granted, yay! Do the 
       // contacts-related task you need to do. 
      } else { 
       // permission denied, boo! Disable the 
       // functionality that depends on this permission. 
      } 
      return; 
     } 
     // other 'case' lines to check for other 
     // permissions this app might request 
    } 
}
