Android之动态申请权限

这篇具有很好参考价值的文章主要介绍了Android之动态申请权限。希望对大家有所帮助。如果存在错误或未考虑完全的地方,请大家不吝赐教,您也可以点击"举报违法"按钮提交疑问。


Android 6.0 (API 23) 之前应用的权限在安装时全部授予,运行时应用不再需要询问用户。在 Android 6.0 或更高版本对权限进行了分类,对某些涉及到用户隐私的权限可在运行时根据用户的需要动态授予。
Android 6.0以下,在AndroidManifest.xml文件中注册权限即可。
Android 6.0及其以后,既要在AndroidManifest.xml文件中注册,又要动态申请危险权限。

如果没有进行动态申请权限将报下面的权限问题的错

1.动态申请权限

打电话的动态申请权限例子

import butterknife.BindView;
import butterknife.ButterKnife;

import static android.os.Build.VERSION_CODES.M;

public class TestActivity extends AppCompatActivity {


    private static final String TAG = "TestActivity";
    private Button mButton;
    //请求码
    private int REQUESTCODE=1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        ButterKnife.bind(this);
        mButton = findViewById(R.id.buttonTest);
       // getExternalFilesDir(Environment.DIRECTORY_PICTURES);

    }

    private void checkPermission() {
        //1.判断当前手机系统是否大于或等于6.0
        //4.如果有打电话的授权,就直接拨打电话
        //1.判断当前手机系统是否大于或等于6.0
        if(Build.VERSION.SDK_INT>=M){
            //2.如果大于6.0,则检查是否有打电话的权限授权
            int isPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE);//用于检测程序是否包含某项权限
            //下面的log如果程序第一次运行checkPermission一般是-1,需要下面的ActivityCompat.requestPermissions去动态
            //申请权限,当你动态申请过一次后下次就不是-1了,除非删掉程序。
            Log.d(TAG, "checkPermission: "+isPermission);
            if(isPermission== PackageManager.PERMISSION_GRANTED){
                //4.如果有打电话的授权,就直接拨打电话
                call();
            }else {
                //3.如果没有打电话的授权,就要去申请打电话的权限
                //下面为申请权限的方法,下面的onRequestPermissionsResult方法用于验证此方法申请成功或失败(到时会弹出一个对话框给你选择允许拒绝)
                //也会导致回调onRequestPermissionsResult方法
                ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.CALL_PHONE},REQUESTCODE);
            }
        }else {
            //5.如果当前版本小于6.0,直接拨打电话
            call();
        }
    }

    /*
    此函数为申请权限的回调方法,无论成功或者失败,都会回调这个方法
    requestCode:上文中提到的请求码
    permissions:申请的权限
    grantResults:申请的结果
     */
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull @NotNull String[] permissions, @NonNull @NotNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if(requestCode==REQUESTCODE){
            if(grantResults!=null&&grantResults.length>0){
                //判断用户是否授予了这个权限
                //因为目前只有打电话这一个权限结果所以使用grantResults[0]
                if(grantResults[0]==PackageManager.PERMISSION_GRANTED){
                    call();
                }else {
                    Toast.makeText(this,"您拒绝了拨打电话的权限",Toast.LENGTH_SHORT).show();
                }
            }
        }
    }

    public void call(){
       //下面这个可以使用this的原因是编译时,他没有new一个实现类或者内部类,不然的话就要类名.this
       //Toast.makeText(this,"你好啊",Toast.LENGTH_SHORT).show();
       Intent intent = new Intent(Intent.ACTION_CALL);
       Uri uri = Uri.parse("tel:" + 1008611);
       intent.setData(uri);
       startActivity(intent);
       Log.d(TAG, "text: "+"跳转了");
   }
    public void text(View view){
       checkPermission();
    }
}

PackageManager.PERMISSION_GRANTED 与 PackageManager.PERMISSION_DENIED ,分别代表着有权限与无权限。通常我们会根据当前权限的状态来决定是否去申请相关权限。

具体内容可看程序注释,比较详细

shouldShowRequestPermissionRationale,回到最初的解释“应不应该解释下请求这个权限的目的”。
1.都没有请求过这个权限,用户不一定会拒绝你,所以你不用解释,故返回false;
2.请求了但是被拒绝了,此时返回true,意思是你该向用户好好解释下了;
(也就是你第一次进行申请的时候弹出的对话框你选择了拒绝,那么就会返回true)
3.请求权限被禁止了,也不给你弹窗提醒了,所以你也不用解释了,故返回fasle;
4.请求被允许了,都给你权限了,还解释个啥,故返回false。
Google的初衷大概就是第一次requestPermissions的时候被拒绝时给你一次解释的机会,所以是让你在请求权限的回调中使用的。文章来源地址https://www.toymoban.com/news/detail-765641.html
