AndroidGUI29：获取ImageView中的图像需要注意的问题(11)

          xmlns:android="http://schemas.android.com/apk/res/android"

          android:layout_width="wrap_content"

          android:layout_height="wrap_content">

                 <Button android:id="@+id/btn_OK"

                          android:layout_width="90dip"

                          android:layout_height="40dip"

                          android:textSize="16dip"

                          android:text="OK"

                 />

        </LinearLayout>

6.     修改TakePicture.java，使其如下：

        package com.waveline.compare2images;

        import android.app.Activity;

        import android.content.Intent;

        import android.graphics.Bitmap;

        import android.graphics.BitmapFactory;

        import android.os.Bundle;

        import android.view.View;

        import android.view.View.OnClickListener;

        import android.widget.Button;

        public class TakePicture extends Activity

        implements

        OnClickListener

        {

                private Intent intent;

                private Button btn_OK;

                @Override

                protected void onCreate(BundlesavedInstanceState)
