这里是xml文件

使用
RelativeLayout
如下:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<me.dm7.barcodescanner.zxing.ZXingScannerView
android:id="@+id/zxscan"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<ImageView
android:id="@+id/btn_flash"
android:layout_marginBottom="15dp"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:src="@drawable/flash_100"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
它看起来像:
应用程序崩溃,它给出“应用程序已停止”请检查我发布的日志删除
setContentView(mScannerView)代码>从java文件替换mScannerView=new ZXingScannerView(此)代码>带有mScannerView=(ZXingScannerView)findViewById(R.id.zxscan)代码>ZXingScannerView zscanner=(ZXingScannerView)findViewById(R.id.zxscan);mScannerView=新ZXingScannerView(此);//以编程方式初始化扫描程序视图zscanner.addView(mScannerView);我在用这个,它能用,行吗?
