PhotoView與GifView的使用

爲了解決圖片的縮放和gif格式的圖片顯示問題，這裏採用了開源庫PhototView(處理圖片縮放問題)和GifView(顯示gif格式圖片)。

PhototView下載路徑，GifView下載路徑，Demo下載路徑

（1）PhotoView加載本地圖片

<span style="font-size:14px;">/**
	 * PhotoView 加載本地圖片
	 */

	private ImageView mImageView;
	<span style="background-color: rgb(255, 255, 255);"><span style="color:#ff0000;">private PhotoViewAttacher mPhotoViewAttacher;</span></span>

	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.photoview_local);
		mImageView = (ImageView) findViewById(R.id.iv_img);
		<span style="color:#ff0000;">mPhotoViewAttacher = new PhotoViewAttacher(mImageView);

		try {
			InputStream inputStream = getAssets().open("testPhotoView.jpg");

			Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
			mImageView.setImageBitmap(bitmap);</span>
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}</span>

（2）、PhotoView加載網絡圖片：

<span style="font-size:14px;">/**
	 * PhotoView 加載網絡圖片
	 */

	<span style="color:#ff0000;">private PhotoView mImageView;
	private PhotoViewAttacher mPhotoViewAttacher;</span>

	private ImageLoader mImageLoader;

	private  String URL = "http://pic3.nipic.com/20090525/2416945_231841034_2.jpg";


	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.photoview_network);

		mImageView = (PhotoView) findViewById(R.id.iv_img);

		<span style="color:#ff0000;">mPhotoViewAttacher = new PhotoViewAttacher(mImageView);
		mImageLoader = ImageLoader.getInstance();
		mImageLoader.displayImage(URL, mImageView);

		mImageView.setOnPhotoTapListener(new OnPhotoTapListener() {
</span>
			@Override
			public void onPhotoTap(View arg0, float arg1, float arg2) {
				// TODO Auto-generated method stub

			}
		});
	}</span>

佈局文件：

<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <uk.co.senab.photoview.PhotoView
        android:id="@+id/iv_img"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

</LinearLayout></span>

（3）GifView加載本地圖片：

<span style="font-size:14px;"><span style="color:#ff0000;">private GifView mGifView;</span>

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.gifview);

		mGifView = (GifView) findViewById(R.id.gifview);
		//加載本地圖片
		<span style="color:#ff0000;">mGifView.setGifImage(R.drawable.gifview);</span>
	}</span>

佈局文件：

<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <com.ant.liao.GifView
        android:id="@+id/gifview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

</LinearLayout></span>
