Android 添加5.0权限

第一步

实现授权回调

public class WelComeActivity extends BasicActivity implements ActivityCompat.OnRequestPermissionsResultCallback

第二步

在initView 判断，如果API》23，请求授权，

@Override
protected void initViews() {

    setContentView(R.layout.activity_wel_come);
    if(Build.VERSION.SDK_INT >= 23){
        if(ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED){
            requestPermission();
        }else {
            getApp().setIMEI();
            AppInfo appInfo = AppInfo.getInstance();
            SharedUtils sharedAppInfoUtil=new SharedUtils(getApplicationContext(), HttpUtil.SHARED_NAME);
            String authorization = sharedAppInfoUtil.getString(BrokerInfoVO.AUTHORIZATION, "");

            appInfo.setAppAuthorization(authorization);
            appInfo.setDeviceId(getApp().IMEI);
            appInfo.setAppVersion(getApp().mVersionName);
        }
    }

第三步

这步让用户去同样授权

private void requestPermission(){
    if(ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.READ_PHONE_STATE)){
        ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.READ_PHONE_STATE},REQUEST_PHONE_STAUS);
    }else {
        ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.READ_PHONE_STATE},REQUEST_PHONE_STAUS);
    }
}

第四步

用户没同意，再次提醒用户给予权限。

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    if(requestCode==REQUEST_PHONE_STAUS){
        if(grantResults.length==1&&grantResults[0]== PackageManager.PERMISSION_GRANTED){
            ToastInfo.shortToast(this,"应用需要权限");
        }else {
            ToastInfo.shortToast(this,"权限没有打开");
        }
    }else {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}
