Java 如何在我的代码中添加棉花糖权限以共享位置？

当我在棉花糖上运行此代码时，此代码在

4.4.2

上运行

shar_btn = (Button) findViewById(R.id.shrbtn);

    shar_btn.setOnClickListener(
            new View.OnClickListener() {
                @Override
                public void onClick(View v) {



                        link = formatLocation(getLocation(), getResources().getStringArray(R.array.link_templates)[0]);
                        Intent intent = new Intent();
                        intent.setAction(Intent.ACTION_SEND);
                        intent.putExtra(Intent.EXTRA_TEXT, link);
                        intent.setType("text/plain");
                        startActivity(Intent.createChooser(intent, getString(R.string.share_location_via)));
                    }

                });
      }

我想这会对你有帮助

你可以这样做

在舱单中：

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

然后对于checkAndRequestPermissions（）函数

/**
 * Check the permission for the ACCESS_FINE_LOCATION
 * if already accepted the permission then pass true
 * else ask permission for the ACCESS_FINE_LOCATION
 *
 * @return
 */
private boolean checkAndRequestPermissions() {
    int externalStoragePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);

    List<String> listPermissionsNeeded = new ArrayList<>();
    if (externalStoragePermission != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
    }

    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_PERMISSIONS);
        return false;
    }
    return true;
}

你的ShareLocation（）就像

您需要在运行时获得权限。具有22以上

targetSdkVersion

的应用程序（如棉花糖和更新版本）需要在运行时请求一些权限。读这本书。只需确保不要将

targetSdkVersion

减少到22，因为这样用户在下载应用程序时需要接受权限，而您不必进行任何其他更改。这将是一个快速、懒惰和错误的方法。非常感谢你的工作。好问题解决了亲爱的
