我要放大圖像放大點擊事件。 我該怎麼做。 這裏是我完整的代碼縮放圖片上的點擊事件
main.xml中
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="fill_parent" android:layout_width="fill_parent" >
<LinearLayout android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button android:text="Button1" android:id="@+id/button1" android:layout_height="wrap_content" android:layout_width="wrap_content" ></Button>
<Button android:text="Button2" android:id="@+id/button2" android:layout_height="wrap_content" android:layout_width="wrap_content" ></Button>
<Button android:text="Button3" android:id="@+id/button3" android:layout_height="wrap_content" android:layout_width="wrap_content" ></Button>
</LinearLayout>
<LinearLayout android:orientation="horizontal"
android:layout_height="290dp"
android:layout_width="wrap_content"
android:layout_gravity="center_horizontal">
<ImageView android:id="@+id/contentImage"
android:layout_height="250dp"
android:layout_width="200dp"
/>
</LinearLayout>
<LinearLayout android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView android:id="@+id/imageView1" android:src="@drawable/img1" android:layout_height="75dp" android:layout_width="75dp" ></ImageView>
<ImageView android:id="@+id/imageView2" android:src="@drawable/img2" android:layout_height="75dp" android:layout_width="75dp" ></ImageView>
<ImageView android:id="@+id/imageView3" android:src="@drawable/img3" android:layout_height="75dp" android:layout_width="75dp" ></ImageView>
</LinearLayout>
</LinearLayout>
聽到的是我的主文件 Image.java在事件將被處理

嗨Nirav Bhaandari ...非常感謝。這段代碼對我真的很有幫助。我在應用程序中找到了解決方案。 – 2011-03-11 12:14:23
