Android一次處理多個運行時權限

從Android6.0開始對於一些危險權限要進行動態處理，這裏寫一個比較簡單的一次處理多個運行時權限的問題，如下：

在Activity中一般在onCreate()方法中來檢查運行時權限問題，直接調用該方法就可以了。

//首先定義一個變量來記錄處理權限了幾次
private int times = 0;
//在處理權限時的回調
private final int REQUEST_PHONE_PERMISSIONS = 0;
//檢查全新的核心方法
private void checkPermission(){
    times++;
    final List<String> permissionsList = new ArrayList<>();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
        if ((checkSelfPermission(Manifest.permission.ACCESS_NETWORK_STATE)!= PackageManager.PERMISSION_GRANTED)) permissionsList.add(Manifest.permission.ACCESS_NETWORK_STATE);
        if ((checkSelfPermission(Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED)) permissionsList.add(Manifest.permission.READ_PHONE_STATE);
        if ((checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED)) permissionsList.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        if ((checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED)) permissionsList.add(Manifest.permission.READ_EXTERNAL_STORAGE);
        if ((checkSelfPermission(Manifest.permission.CAMERA)!= PackageManager.PERMISSION_GRANTED)) permissionsList.add(Manifest.permission.CAMERA);
        if ((checkSelfPermission(Manifest.permission.BLUETOOTH)!= PackageManager.PERMISSION_GRANTED)) permissionsList.add(Manifest.permission.BLUETOOTH);
        if ((checkSelfPermission(Manifest.permission.RECORD_AUDIO)!= PackageManager.PERMISSION_GRANTED)) permissionsList.add(Manifest.permission.RECORD_AUDIO);
        if (permissionsList.size() != 0){
            if(times==1){
                requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                        REQUEST_PHONE_PERMISSIONS);
            }else{
                new AlertDialog.Builder(this)
                        .setCancelable(true)
                        .setTitle("提示")
                        .setMessage("獲取不到授權，APP將無法正常使用，請允許APP獲取權限！")
                        .setPositiveButton("確定", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface arg0, int arg1) {
                                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                                    requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                                            REQUEST_PHONE_PERMISSIONS);
                                }
                            }
                        }).setNegativeButton("取消", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface arg0, int arg1) {
                        finish();//這裏對該界面直接進行銷燬，讓用戶從新進入該界面
                    }
                }).show();
            }
        }else{
            //initData();//初始化數據
        }
    }else{
        //initData();//初始化數據
    }
}

//權限處理的回調
@Override
public void onRequestPermissionsResult(int requestCode,  final String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    checkPermission();
}
