动态获取权限工具类及其使用

来源：互联网发布：java template 编辑：程序博客网时间：2024/05/18 18:44

当前手机各种系统权限比较多，很多时候需要动态的获取一些系统权限，添加其中，为此在写很多APP的时候需要在APP首个界面检查添加权限，所以自己封装了一个根据类。

PermissionUtils类

package com.fly.fengtaobao.utils;import android.annotation.TargetApi;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.content.pm.PackageManager;import android.net.Uri;import android.os.Build;import android.provider.Settings;import android.support.v4.content.ContextCompat;import java.util.ArrayList;import java.util.List;/** * <pre> *           .----. *        _.'__    `. *    .--(Q)(OK)---/$\ *  .' @          /$$$\ *  :         ,   $$$$$ *   `-..__.-' _.-\$$$/ *         `;_:    `"' *       .'"""""`. *      /,  FLY  ,\ *     //         \\ *     `-._______.-' *     ___`. | .'___ *    (______|______) * </pre> * 包    名 : com.fly.fengtaobao.utils * 作    者 : FLY * 创建时间 : 2017/8/3 * <p> * 描述: 动态获取权限 */public class PermissionUtils {    public static final int SETTING_REQUEST_CODE = 1111;    /**     * 获取请求权限中需要授权的权限     * @param context     * @param permissions 一个或多个权限     * @return     */    public static List<String> getDeniedPermissions(Context context,String... permissions){        List<String> deniedPermissions = new ArrayList<String>();        for (String permission : permissions) {            //判断权限是否授予            if (ContextCompat.checkSelfPermission(context,permission)== PackageManager.PERMISSION_DENIED){                deniedPermissions.add(permission);            }        }        return deniedPermissions;    }    /**     * 授权权限     * @param activity     * @param permission_request_code     * @param permissions     * @return     */    @TargetApi(Build.VERSION_CODES.M)    public static boolean isPermissionsGranted(Activity activity,int permission_request_code,String... permissions){        List<String> deniedPermissions = PermissionUtils.getDeniedPermissions(activity,permissions);        if (deniedPermissions != null && deniedPermissions.size()>0){            activity.requestPermissions(                    deniedPermissions.toArray(new String[deniedPermissions.size()])                    ,permission_request_code);            //授权Activity回调        }else {            //权限通过            return true;        }        return false;    }    /**     * 验证所有权限是否都已经授权     * @param grantResults     * @return     */    public static boolean verifyPermissions(int[] grantResults){        for (int grantResult:grantResults) {            if (grantResult != PackageManager.PERMISSION_DENIED){                return false;            }        }        return true;    }    /**     * 显示提示对话框     * @param context     */    public static void showTipsDialog(Activity context){        LibDialogUtils.showPermissionTipsDialog(context);    }    public static void startAppSettings(Activity context){        Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);        intent.setData(Uri.parse("package:"+context.getPackageName()));        //得到新打开Activity关闭后返回的数据        //第二个参数为请求码，可以根据业务需求自己编号        context.startActivityForResult(intent,SETTING_REQUEST_CODE);        context.startActivity(intent);    }}

LibDialogUtils类

package com.fly.fengtaobao.utils;import android.app.Activity;import android.app.AlertDialog;import android.content.DialogInterface;import com.fly.fengtaobao.R;/**  * <pre> *           .----. *        _.'__    `. *    .--(Q)(OK)---/$\ *  .' @          /$$$\ *  :         ,   $$$$$ *   `-..__.-' _.-\$$$/ *         `;_:    `"' *       .'"""""`. *      /,  FLY  ,\ *     //         \\ *     `-._______.-' *     ___`. | .'___ *    (______|______) * </pre> * 包    名 : com.fly.fengtaobao.utils * 作    者 : FLY * 创建时间 : 2017/8/4 * <p> * 描述: Dialog工具类 */public class LibDialogUtils {    public static void showPermissionTipsDialog(final Activity activity){        new AlertDialog.Builder(activity)                .setTitle(R.string.LibDialogUtils_showPermissionTipsDialog_title)                .setMessage(R.string.LibDialogUtils_showPermissionTipsDialog_message)                .setPositiveButton(R.string.LibDialogUtils_showPermissionTipsDialog_yes, new DialogInterface.OnClickListener() {                    @Override                    public void onClick(DialogInterface dialog, int which) {                        PermissionUtils.startAppSettings(activity);                    }                }).show();    }}

SplashActivity使用地方

package com.fly.fengtaobao.View;import android.content.Intent;import android.os.Bundle;import android.support.annotation.NonNull;import android.view.WindowManager;import com.fly.fengtaobao.R;import com.fly.fengtaobao.View.base.BaseActivity;import com.fly.fengtaobao.View.common.config.Config;import com.fly.fengtaobao.utils.PermissionUtils;/** * <pre> *           .----. *        _.'__    `. *    .--(Q)(OK)---/$\ *  .' @          /$$$\ *  :         ,   $$$$$ *   `-..__.-' _.-\$$$/ *         `;_:    `"' *       .'"""""`. *      /,  FLY  ,\ *     //         \\ *     `-._______.-' *     ___`. | .'___ *    (______|______) * </pre> * 创建时间 : 2017/7/26 * <p> * 描述: View --> 闪屏 * 1.动态权限的获取 * 2.判断是否可以正常获取到 手机串号 */public class SplashActivity extends BaseActivity {    /**     * 要动态获取权限时,延时100毫秒,进入下一个页面     */    private static final long DELAY_MILLIS_PERMISSION = 100;    /**     * 正常情况下,延时1300毫秒,进入下一个页面     */    private static final long DELAY_MILLIS = 500;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //取消状态栏        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                WindowManager.LayoutParams.FLAG_FULLSCREEN);        setContentView(R.layout.activity_splash);        /**         * 获取权限         */        takePermission();    }    private void init() {    }    private void takePermission() {        if (PermissionUtils.isPermissionsGranted(this, Config.SPLASH_ACTIVITY_PERMISSION_REQUEST_CODE                , Config.mPermissionsSplashActivity)) {            onPermissionsGranted();        }    }    private void onPermissionsGranted() {        init();    }    private void onPermissionsDenied() {        PermissionUtils.showTipsDialog(this);    }    /**     * 申请权限的回调     */    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        super.onRequestPermissionsResult(requestCode, permissions, grantResults);        if (requestCode == Config.SPLASH_ACTIVITY_PERMISSION_REQUEST_CODE) {            if (PermissionUtils.verifyPermissions(grantResults)) {                onPermissionsGranted();            } else {                onPermissionsDenied();            }        }    }    /**     * 从设置界面回来之后的回调,重新验证权限是否获取到     */    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode, data);        if (requestCode == PermissionUtils.SETTING_REQUEST_CODE) {            takePermission();        }    }}
