Android RuntimePermissions运行时权限:批量权限申请
绝大多数情况一个APP不可能只有单个权限,往往需要运行时批量申请n多个权限。比如在Androidmanifest里面写了两个权限:
<uses-permission android:name="android.permission.CAMERA"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
那么在运行时申请权限,要点是把全部权限装入到一个String数据里面,批量做一次申请:
package zhangphil.permission; import android.Manifest; import android.os.Build; import android.support.v4.app.ActivityCompat; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; public class MainActivity extends AppCompatActivity { private final String TAG = "ZHANG PHIL"; private final int PERMISSION_REQUEST = 0xa00; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, PERMISSION_REQUEST); } } @Override public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { switch (requestCode) { case PERMISSION_REQUEST: if (grantResults != null && permissions != null) { for (int i = 0; i < grantResults.length; i++) { Log.d(TAG, "grantResults[" + i + "]:" + grantResults[i]); Log.d(TAG, "permissions[" + i + "]:" + permissions[i]); } } break; } } }
代码运行结果logcat输出:
09-25 11:10:17.354 14247-14247/zhangphil.permission D/ZHANG PHIL: grantResults[0]:0 09-25 11:10:17.355 14247-14247/zhangphil.permission D/ZHANG PHIL: permissions[0]:android.permission.CAMERA 09-25 11:10:17.355 14247-14247/zhangphil.permission D/ZHANG PHIL: grantResults[1]:0 09-25 11:10:17.355 14247-14247/zhangphil.permission D/ZHANG PHIL: permissions[1]:android.permission.WRITE_EXTERNAL_STORAGE
