随记7——Android6.0动态权限申请

女神镇楼

Android6.0之后，增强了权限管理，有些权限（比如拍照、打电话等）只在AndroidManifest.xml中声明已经不可以了，需要动态申请。以下就以打电话为例看一看如何动态申请6.0的打电话权限。

如下：

1、先检查权限，没有的话请求权限

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                    // TODO: Consider calling
                    //    ActivityCompat#requestPermissions
                    // here to request the missing permissions, and then overriding
                    //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                    //                                          int[] grantResults)
                    // to handle the case where the user grants the permission. See the documentation
                    // for ActivityCompat#requestPermissions for more details.

                    requestPermissions(new String[]{Manifest.permission.CALL_PHONE}, 100);
                    return;
                }
                Intent intent_5 = new Intent(Intent.ACTION_CALL, Uri.parse("tel:123456789"));
                startActivity(intent_5);

2、根绝返回结果处理

 @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == 100 && grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Intent intent_5 = new Intent(Intent.ACTION_CALL, Uri.parse("tel:123456789"));
            startActivity(intent_5);
        }else{
            Log.e("aaa", "没有打电话权限");
        }
    }

就是这样。白了个白！
