感谢大佬，另外问一下像支付宝那样对相机界面更改是怎么做到的[/quote]你是指拍摄身份证页面？那是自定义相机，调用摄像头，显示到界面上，原理类似二维码扫描。

打开相机是这个

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

如果你的MainActivity不是自定义照相机，删除下面代码

            <intent-filter>
                <action android:name="android.media.action.IMAGE_CAPTURE" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
