PhotoView与GifView的使用

为了解决图片的缩放和gif格式的图片显示问题，这里采用了开源库PhototView(处理图片缩放问题)和GifView(显示gif格式图片)。

1、PhotoView加载本地图片

/**
 * PhotoView 加载本地图片
 */

private ImageView mImageView;
private PhotoViewAttacher mPhotoViewAttacher;

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);
    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();
    }
}

2、PhotoView加载网络图片：

/**
 * PhotoView 加载网络图片
 */

private PhotoView mImageView;
private PhotoViewAttacher mPhotoViewAttacher;

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);

    mPhotoViewAttacher = new PhotoViewAttacher(mImageView);
    mImageLoader = ImageLoader.getInstance();
    mImageLoader.displayImage(URL, mImageView);

    mImageView.setOnPhotoTapListener(new OnPhotoTapListener() {

        @Override
        public void onPhotoTap(View arg0, float arg1, float arg2) {
            // TODO Auto-generated method stub

        }
    });
}

布局文件：

<?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加载本地图片：

private GifView mGifView;
@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);
    //加载本地图片
    mGifView.setGifImage(R.drawable.gifview);
}

布局文件：

<?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>
