Android权限获取

开发中，很多时候要去动态的获取权限，效果图如下：

直接看代码，首先加入权限：
 

    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.WRITE_SETTINGS" />
    <uses-permission android:name="android.permission.REORDER_TASKS" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />

    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.FLASHLIGHT" />
    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
    <uses-permission android:name="android.permission.SEND_DOWNLOAD_COMPLETED_INTENTS" />
    <!-- 访问网络的权限 -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.READ_LOGS" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" />
    <uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

    <uses-feature android:name="android.hardware.location.gps" />

    <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <!-- 阅读消息 -->
    <uses-permission android:name="android.permission.READ_SMS" />
    <!-- 写入消息 -->
    <uses-permission android:name="android.permission.WRITE_SMS" />
    <!-- 接收消息 -->
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <!-- iBeancon功能所需权限 -->
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

然后加入权限管理的工具类：
 

import android.content.Context;
import android.content.pm.PackageManager;
import android.support.v4.content.ContextCompat;

/**
 * author: wu
 * date: on 2018/11/30.
 * describe:检查权限的工具类
 */

public class PermissionsChecker {
    private final Context mContext;

    public PermissionsChecker(Context context) {
        mContext = context.getApplicationContext();
    }

    // 判断权限集合
    public boolean lacksPermissions(String... permissions) {
        for (String permission : permissions) {
            if (lacksPermission(permission)) {
                return true;
            }
        }
        return false;
    }

    // 判断是否缺少权限
    private boolean lacksPermission(String permission) {
        return ContextCompat.checkSelfPermission(mContext, permission) ==
                PackageManager.PERMISSION_DENIED;
    }
}

最后在代码中应用工具类：
 

public class MainActivity extends AppCompatActivity {
    private PermissionsChecker mPermissionsChecker; // 权限检测器
    private final int RESULT_CODE_LOCATION = 0x001;
    private Button button;
    //定位权限,获取app内常用权限
    String[] permsLocation = {"android.permission.READ_PHONE_STATE"
            , "android.permission.ACCESS_COARSE_LOCATION"
            , "android.permission.ACCESS_FINE_LOCATION"
            , "android.permission.READ_EXTERNAL_STORAGE"
            , "android.permission.WRITE_EXTERNAL_STORAGE"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button = findViewById(R.id.button);
        mPermissionsChecker = new PermissionsChecker(MainActivity.this);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (mPermissionsChecker.lacksPermissions(permsLocation)) {
                    ActivityCompat.requestPermissions(MainActivity.this, permsLocation, RESULT_CODE_LOCATION);
                }
            }
        });
    }
}

这样就可以了~~
