描述:適配6.0以下和6.0以上動(dòng)態(tài)權(quán)限,并可以解決6.0以上個(gè)別手機(jī)點(diǎn)拒絕權(quán)限后會(huì)返回權(quán)限允許的回調(diào)的問題,例如:OnePlus3T（一加） A3010 7.1.1系統(tǒng)

以撥打電話為例:(注:直接撥打電話需要?jiǎng)討B(tài)權(quán)限判斷,喚起撥打電話界面不需要)

一.在build.gradle中添加依賴:

//RxPermissions
compile 'com.tbruyelle.rxpermissions2:rxpermissions:0.9.3@aar'
 //RxJava2
implementation "io.reactivex.rxjava2:rxjava:2.0.0"

另外用到了JDK1.8的新特性,也需要在build.gradle中android節(jié)點(diǎn)下配置

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

二.工具類

/**
 * Created by caoshiyao on 2018/9/6.
 * Android6.0權(quán)限申請工具類
 */
public class PermissionUtil {

    public interface IPermissionListener {

        //權(quán)限被授權(quán)
        void permissionGranted();

        //權(quán)限被拒絕
        void permissionDenied();
    }

    /**
     * 申請獲取相關(guān)權(quán)限
     *
     * @param context
     * @param iPermissionListener
     * @param toastDetails
     * @param permissions
     */
    public static void requestPermission(@NonNull Context context, @NonNull IPermissionListener iPermissionListener, @NonNull String toastDetails, @NonNull String... permissions) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
            iPermissionListener.permissionGranted();
        } else {
            new RxPermissions((Activity) context)
                    .request(permissions)
                    .subscribe(granted -> {
                        if (granted) {
                            if (hasOpsPermission(context, permissions)) {
                                iPermissionListener.permissionGranted();
                            } else {
                                iPermissionListener.permissionDenied();
                                ToastUtil.showToast(context, toastDetails);
                            }
                        } else {
                            iPermissionListener.permissionDenied();
                            ToastUtil.showToast(context, toastDetails);
                        }
                    });
        }
    }

    /**
     * Android6.0權(quán)限申請后再判斷原生的權(quán)限是否真的被授權(quán)--適配部分國產(chǎn)機(jī)型（小米方库、華為泣港、vivo谒臼、oppo等）
     *
     * @param context
     * @param permissions
     * @return
     */
    private static boolean hasOpsPermission(@NonNull Context context, @NonNull String... permissions) {
        for (String permission : permissions) {
            String op = AppOpsManagerCompat.permissionToOp(permission);
            int result = AppOpsManagerCompat.noteProxyOp(context, op, context.getPackageName());
            if (result == AppOpsManagerCompat.MODE_ALLOWED) return true;
        }
        return false;
    }

}

三.使用方法:

    /**
     * 檢查權(quán)限
     */
    private void checkPermission() {
        PermissionUtil.requestPermission(this, new PermissionUtil.IPermissionListener() {
            @Override
            public void permissionGranted() {
                call();
            }

            @Override
            public void permissionDenied() {
                ToastUtil.showToast(PermissionActivity.this,"權(quán)限被拒絕");
            }
        },"權(quán)限被拒絕,請?jiān)O(shè)置應(yīng)用權(quán)限",Manifest.permission.CALL_PHONE);
    }

    /**
     * 撥打電話,直接撥打出去
     */
    private void call() {
        try {
            Intent intent = new Intent(Intent.ACTION_CALL);
            Uri uri = Uri.parse("tel:" + "10086");
            intent.setData(uri);
            startActivity(intent);
        } catch (SecurityException e) {
            e.printStackTrace();
        }
    }
