1.首先確定你要申請(qǐng)的權(quán)限

可以定義成一個(gè)數(shù)組：如

protected String[] needPermissions = {
? ? ? ? ? ? Manifest.permission.WRITE_EXTERNAL_STORAGE,//存儲(chǔ)卡寫入權(quán)限
? ? ? ? ? ? Manifest.permission.READ_EXTERNAL_STORAGE,//存儲(chǔ)卡讀取權(quán)限
? ? ? ? ? ? Manifest.permission.READ_PHONE_STATE,//讀取手機(jī)狀態(tài)權(quán)限
? ? };

上訴權(quán)限是一個(gè)常量字符串，需要引入?import android.Manifest;

2.檢測(cè)權(quán)限有沒(méi)有獲取到，找出沒(méi)獲取到的去申請(qǐng)

private List<String> checkGamePer(){
? ? ? ? List<String> arr = new ArrayList<String>();
? ? ? ? for (String perm : needPermissions) {

? ? ? ? ? ? ? ? //this參數(shù)要activity
? ? ? ? ? ? if (ContextCompat.checkSelfPermission(this, perm) != PackageManager.PERMISSION_GRANTED ) {
? ? ? ? ? ? ? ? arr.add(perm);
? ? ? ? ? ? }
? ? ? ? }
? ? ? ? return arr;
? ? }

?List<String> arr = checkGamePer();
? ? ? ? if (arr.size()>0) {
? ? ? ? ? ? // 還有權(quán)限沒(méi)申請(qǐng)到，則申請(qǐng)權(quán)限,? this參數(shù)要activity
? ? ? ? ? ? ActivityCompat.requestPermissions(this, arr.toArray(new String[arr.size()]), 1);
? ? ? ? } else {
? ? ? ? ? ?//權(quán)限都申請(qǐng)到了，直接做你想做的事
? ? ? ? }

3.玩家點(diǎn)擊同意或者拒絕權(quán)限后會(huì)回調(diào)，在上訴this的activity中注冊(cè)回調(diào)函數(shù)

public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        if (requestCode == 1) {
            Boolean flag = true;
            for (int i = 0; i < permissions.length; i++) {
                if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {//選擇了“始終允許”
                    flag = false;
                }
            }
            if (flag) {
                //申請(qǐng)成功
                
            } else {
                //失敗  退出游戲
                finish();
            }
        }
    }

這里的requestCode就是請(qǐng)求權(quán)限時(shí)，傳入的參數(shù)?

            String[] temp = new String[mNeedRequestPMSList.size()];
            mNeedRequestPMSList.toArray(temp);
            ActivityCompat.requestPermissions(MainActivity.activity, temp, requestCode);
        }
    }

        Boolean flag = true;
        for (int i = 0; i < permissions.length; i++) {
            if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {//選擇了“始終允許”
                flag = false;
            }
        }
        switch (requestCode) {
