許可權檢查一般放在APP的入口，比如說閃屏頁splashactivity中或者baseapplication中。

    其中需要兩個類，一個是PermissionChecker，一個是PermissionsActivity。第一個是用來檢測當前是否已經獲取到了申請的許可權，如果沒有則跳轉到許可權申請類PermissionsActivity中進行開啟所需許可權。

直接上程式碼吧，第一個PermissionChecker

package tv.talkweb.daddygowhere.util.permissioncheck;

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

/**
 *  檢查許可權的工具類
 * Created by su on 2017/1/22.
 */

public class PermissionsChecker {
	private final Context mContext;

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

	// 判斷許可權集合
	public boolean lacksPermissions(String... permissions) {
		for (String permission : permissions) {
			if (lacksPermission(permission)) {
				return true;
			}
		}
		return false;
	}

	// 判斷是否缺少許可權
	private boolean lacksPermission(String permission) {
		return ContextCompat.checkSelfPermission(mContext, permission) ==
				PackageManager.PERMISSION_DENIED;
	}
}
 

package tv.talkweb.daddygowhere.util.permissioncheck;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;

具體使用：

列出所有需要啟動的許可權

建立許可權檢測器成員變數

在onCreate中初始化成員變數

在onResume中檢測並處理缺少的許可權

public class ActivitySplash extends BaseActivity implements UmengUtil.MyUmengOnlineConfigListener{

    private Context context;
    private CountdownView splashCircleView;
    // 所需的全部許可權
    static final String[] PERMISSIONS = new String[]{
            Manifest.permission.RECORD_AUDIO,
            Manifest.permission.MODIFY_AUDIO_SETTINGS,
            Manifest.permission.READ_PHONE_STATE,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.ACCESS_NETWORK_STATE,
            Manifest.permission.ACCESS_WIFI_STATE,
            Manifest.permission.ACCESS_FINE_LOCATION
    };
    private static final int REQUEST_CODE = 0; // 請求碼

    private PermissionsChecker mPermissionsChecker; // 許可權檢測器

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.context = this;
        mPermissionsChecker = new PermissionsChecker(this);

    protected void onResume() {
        super.onResume();
        // 缺少許可權時, 進入許可權配置頁面
        if (Build.VERSION.SDK_INT > 22){
            if (mPermissionsChecker.lacksPermissions(PERMISSIONS)) {
                startPermissionsActivity();
            }
        }
    }

    private void startPermissionsActivity() {
        PermissionsActivity.startActivityForResult(this, REQUEST_CODE, PERMISSIONS);
		}
