我正在开发一个
Android应用程序,其中需要提供读写外部存储的权限.我的要求是从图库中选择一张图片并在我的应用中使用它.除了棉花糖设备,一切都很好.我想为Marshmallow提供许可.谁能帮我这个？
解决方法
它可以实现如下……
- public class MainActivity extends AppCompatActivity implements ActivityCompat.OnRequestPermissionsResultCallback{
- private static final int REQUEST_WRITE_PERMISSION = 786;
- @Override
- public void onRequestPermissionsResult(int requestCode,String[] permissions,int[] grantResults) {
- if (requestCode == REQUEST_WRITE_PERMISSION && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
- openFilePicker();
- }
- }
- @Override
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_main);
- requestPermission();
- }
- private void requestPermission() {
- if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
- requestPermissions(new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE},REQUEST_WRITE_PERMISSION);
- } else {
- openFilePicker();
- }
- }
- }
