RxPermissions使用

 RxPermissions使用

基于RxJava2，使用包名为com.tbruyelle.rxpermissions2的RxPermissions。

5.1 App module的build.gradle

dependencies {
    ...
    compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
    compile 'io.reactivex.rxjava2:rxjava:2.0.5'
    compile 'com.tbruyelle.rxpermissions2:rxpermissions:0.9.3@aar'
    ...
}

5.2 AndroidManifest.xml中使用权限

5.3 在Activity的onCreate()中申请权限

package com.galian.rxjavatest;

import android.Manifest;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import com.tbruyelle.rxpermissions2.Permission;
import com.tbruyelle.rxpermissions2.RxPermissions;

import io.reactivex.functions.Consumer;

public class RxPermissionTestActivity extends AppCompatActivity {

    private static final String TAG = "RxPermissionTest";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_rx_permission_test);

        requestPermissions();
    }

    private void requestPermissions() {
        RxPermissions rxPermission = new RxPermissions(RxPermissionTestActivity.this);
        rxPermission
                .requestEach(Manifest.permission.ACCESS_FINE_LOCATION,
                        Manifest.permission.WRITE_EXTERNAL_STORAGE,
                        Manifest.permission.READ_CALENDAR,
                        Manifest.permission.READ_CALL_LOG,
                        Manifest.permission.READ_CONTACTS,
                        Manifest.permission.READ_PHONE_STATE,
                        Manifest.permission.READ_SMS,
                        Manifest.permission.RECORD_AUDIO,
                        Manifest.permission.CAMERA,
                        Manifest.permission.CALL_PHONE,
                        Manifest.permission.SEND_SMS)
                .subscribe(new Consumer() {
                    @Override
                    public void accept(Permission permission) throws Exception {
                        if (permission.granted) {
                            // 用户已经同意该权限
                            Log.d(TAG, permission.name + " is granted.");
                        } else if (permission.shouldShowRequestPermissionRationale) {
                            // 用户拒绝了该权限，没有选中『不再询问』（Never ask again）,那么下次再次启动时。还会提示请求权限的对话框
                            Log.d(TAG, permission.name + " is denied. More info should be provided.");
                        } else {
                            // 用户拒绝了该权限，而且选中『不再询问』
                            Log.d(TAG, permission.name + " is denied.");
                        }
                    }
                });


    }
