Android动态申请权限(一次申请多个动态权限)

Android 6.0也就是API等级23之后，获取权限需要动态申请，否则程序无法正常使用。

录像需要多个权限，下面是一次申请多个权限的代码，单个权限申请也是差不多的：

package com.barrage.barragetest;

import android.Manifest;

import android.content.DialogInterface;

import android.content.Intent;

import android.content.pm.PackageManager;

import android.net.Uri;

import android.os.Build;

import android.os.Bundle;

import android.provider.Settings;

import android.support.annotation.NonNull;

import android.support.v4.app.ActivityCompat;

import android.support.v7.app.AlertDialog;

import android.support.v7.app.AppCompatActivity;

import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

//录像需要的权限

private static final String[] VIDEO_PERMISSIONS = {Manifest.permission.CAMERA,Manifest.permission.RECORD_AUDIO,Manifest.permission.WRITE_EXTERNAL_STORAGE};

private static final int VIDEO_PERMISSIONS_CODE = 1;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

requestPermission();

}

//申请权限

private void requestPermission() {

// 当API大于 23 时，才动态申请权限

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

ActivityCompat.requestPermissions(MainActivity.this,VIDEO_PERMISSIONS,VIDEO_PERMISSIONS_CODE);

}

}

@Override

public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

super.onRequestPermissionsResult(requestCode, permissions, grantResults);

switch (requestCode) {

case VIDEO_PERMISSIONS_CODE:

//权限请求失败

if (grantResults.length == VIDEO_PERMISSIONS.length) {

for (int result : grantResults) {

if (result != PackageManager.PERMISSION_GRANTED) {

//弹出对话框引导用户去设置

showDialog();

Toast.makeText(MainActivity.this, "请求权限被拒绝", Toast.LENGTH_LONG).show();

break;

}

}

}else{

Toast.makeText(MainActivity.this, "已授权", Toast.LENGTH_LONG).show();

}

break;

}

}

//弹出提示框

private void showDialog(){

AlertDialog dialog = new AlertDialog.Builder(this)

.setMessage("录像需要相机、录音和读写权限，是否去设置？")

.setPositiveButton("是", new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

dialog.dismiss();

goToAppSetting();

}

})

.setNegativeButton("否", new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

dialog.dismiss();

}

})

.setCancelable(false)

.show();

}

// 跳转到当前应用的设置界面

private void goToAppSetting(){

Intent intent = new Intent();

intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);

Uri uri = Uri.fromParts("package", getPackageName(), null);

intent.setData(uri);

startActivity(intent);

}

}

另外还需要在AndroidManifest.xml中添加相应的权限：
