效果果：

1.清单文件

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.CAMERA" />

2.调用申请权限的方法

public class MainActivity extends AppCompatActivity {
    final String[] PERMISSIONS = new String[]{
            Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.CAMERA,
            Manifest.permission.ACCESS_COARSE_LOCATION,
            Manifest.permission.ACCESS_FINE_LOCATION,
    };

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

    //检查所需的全部权限
    public boolean doCheckPermission() {
        PermissionsChecker mPermissionsChecker = new PermissionsChecker(MainActivity.this);
        if (mPermissionsChecker.lacksPermissions(PERMISSIONS)) {
            ActivityCompat.requestPermissions(MainActivity.this, PERMISSIONS, 0x12);
            return false;
        }
        return true;
    }
}

3.权限类


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


public class PermissionsChecker {
    private final Context mContext;

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

    // 判断权限集合
    public boolean lacksPermissions(String... permissions) {
        for (String permission : permissions) {
            if (lacksPermission(permission)) {
                return true;
            }
        }
        return false;
    }

    // 判断是否缺少权限
    private boolean lacksPermission(String permission) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            return ContextCompat.checkSelfPermission(mContext, permission) ==
                    PackageManager.PERMISSION_DENIED;
        }
        return false;
    }

}
