动态权限申请小结

单个权限推荐

if (ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.CAMERA)

!= PackageManager.PERMISSION_GRANTED) {

ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CAMERA}, 100);

return;

}

多个权限：

//定义权限数组
public final String[]authBaseArr = {

Manifest.permission.WRITE_EXTERNAL_STORAGE,

        Manifest.permission.ACCESS_FINE_LOCATION

};

//申请

if (android.os.Build.VERSION.SDK_INT >=23) {

this.requestPermissions(authBaseArr, 100);

return;

}

//重写

@Override

public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {

super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    if (requestCode ==100) {

Log.d("tag",grantResults.toString());

        for (int ret : grantResults) {

if (ret ==0) {

continue;

            }else {

Toast.makeText(MainActivity.this, "缺少导航基本的权限!", Toast.LENGTH_SHORT).show();

return;

            }

}

}

}
