Click Download ZIP to download:
put all the folders under the libs folder Copy it to the project directory libs (eg: .\Dp Notes\libs), copy the lp folder under src to the project directory src (eg: .\Dp Notes\src).
Right-click on the ADT project name to refresh:
Well, a bunch of errors were reported. It should be that the library has been updated. The main reason for the error is that the SDK version of ADT is too low. The solution is of course to update the SDK (update is too slow? Forget it, no updated), each file is corrected.
First of all, import android.support.annotation.x reports an error:
Baidu, download support-annotations-23.0.1.jar and put it under libs, address: http://download.csdn.net/download/lvshaorong/9399501, CSDN points-free .
Then, something like final ConcurrentLinkedQueue<AnimationListener> mListeners = new ConcurrentLinkedQueue<AnimationListener>();
Similar to catch (Exception ignored)
Similar to
// @TargetApi(Build.VERSION_CODES.LOLLIPOP)
// public GifImageView(Context context, AttributeSet attrs, int defStyle, int defStyleRes) {
// super(context, attrs, defStyle, defStyleRes);
/ / postInit(GifViewUtils.initImageView(this, attrs, defStyle, defStyleRes));
// }
Finally, bold comments that are wrong, so far.
Simple display test, the last addition to Activity_main.xml:
<pl.droidsonroids.gif.GifImageView android:id="@+id/giv_demo" android:layout_width="match_parent" android:layout_height="match_parent" android:src="@drawable/gif_smaple"/>
gif_smaple is a GIF animation file, run:
Note: This is a .gif animation, ctrl click on the picture to view
the ADT tool is really going to be eliminated, the last time it is used.
How does the code add a GifImageView and display a moving image? In fact, just like the control that comes with Android, you can set a new property, which is directly implemented in the ListView Item in the previous section:
if("gif".equals(data.type)){//To display GIF
if(holder.tv_gifctrl!=null){//GIF control is removed first
holder.rl_data.removeView(holder.tv_gifctrl);
}
if(holder.giv_data!=null){//GIF display first removed
holder.giv_data.setVisibility(View.GONE);
}
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
holder.tv_gifctrl=new TextView(activity);//Generate GIF control
holder.tv_gifctrl.setText("GIF");//Set some TextView properties
holder.tv_gifctrl.setGravity(Gravity.CENTER_HORIZONTAL);
holder.tv_gifctrl.setTextColor(activity.getResources().getColor(R.color.white_dark));
holder.tv_gifctrl.setTextSize(TypedValue.COMPLEX_UNIT_PX,activity.getResources().getDimension(R.dimen.text_level1));
int padding=(int)activity.getResources().getDimension(R.dimen.padding_n);
GradientDrawable gd = new GradientDrawable();
gd.setColor(activity.getResources().getColor(R.color.black_normal_88));
gd.setCornerRadius(padding);
holder.tv_gifctrl.setBackground(gd);//Set the background of rounded corners
holder.tv_gifctrl.setPadding(padding,padding,padding,padding);
lp1.addRule(RelativeLayout.CENTER_IN_PARENT);
holder.tv_gifctrl.setLayoutParams (lp1);
holder.tv_gifctrl.setTag(tagctrlgif);//Set TAG
holder.rl_data.addView(holder.tv_gifctrl);//Add to layout
OnClickListener listener=new OnClickListener() {//Click listener
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
v.setOnClickListener(null);//Clear the listener
v.findViewWithTag(tagctrlgif).setVisibility(View.GONE);//Find GIF control through TAG, hide
if(holder.giv_data!=null){ //GIF display first remove
holder.rl_data.removeView(holder.giv_data);
}
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
//Generate GIF display
holder.giv_data=new GifImageView(activity);
holder.giv_data.setLayoutParams (lp);
holder.giv_data.setTag (tagdata); // 设置 TAG
holder.rl_data.addView(holder.giv_data);//Add to the layout
//Load GIF image resource
GifDrawable drawable=gifload.loadImage(viewparent,tagdata,data.dataurl,glcallback);
if(drawable!=null){//Already loaded
drawable.start();//Start playing, set
holder.giv_data.setBackground(drawable);
}
else{//Add a progress bar
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
holder.pb_load=new ProgressBar(activity,null,android.R.attr.progressBarStyleSmall);
lp1.addRule(RelativeLayout.CENTER_IN_PARENT);
holder.pb_load.setLayoutParams(lp1);
holder.pb_load.setTag(tagloadgif);
holder.rl_data.addView(holder.pb_load);
}
}
};
holder.rl_data.setOnClickListener(listener);//Set the listener
}
A GIF loaded listener similar to when the image is loaded:
private GifLoadCallback glcallback=new GifLoadCallback() {
@SuppressLint("NewApi")
@Override
public void onSuccess(GifDrawable drawable, int tag, View viewParent) {
// TODO Auto-generated method stub
if(drawable!=null){
//Find the GIF display by TAG
GifImageView giv_data=(GifImageView)viewParent.findViewWithTag(tag);
if(giv_data!=null){//Find, set display
// LayoutParams lp=rl_data.getLayoutParams();
// lp.height=itemWidth*drawable.getMinimumHeight()/drawable.getMinimumWidth();
// rl_data.setLayoutParams (lp);
drawable.start();
giv_data.setBackground(drawable);
viewParent.findViewWithTag(tag+1).setVisibility(View.GONE);//GIF control hidden
viewParent.findViewWithTag(tag-1).setVisibility(View.GONE);//GIF loading progress bar is hidden
}
}
}
};
Attach the class loaded by GifDrawable, similar to the loading of image Drawable:
public class GifLoad {

private Map<String, GifDrawable> imageMap;

@SuppressLint("NewApi")
public GifLoad(Context context){
this.context=context;
imageMap=new LinkedHashMap<String, GifDrawable>();
queue =new ArrayBlockingQueue<Runnable>(this.threadMaxNum);
executor=new ThreadPoolExecutor(this.threadMaxNum,this.threadMaxNum,1,TimeUnit.MINUTES,queue,new ThreadPoolExecutor.CallerRunsPolicy());
// File dir=new File(this.path);
// if(!dir.exists()){
// dir.mkdirs();
// }
}
public void setcacheMaxNum(int maxNum){
this.cacheMaxNum=maxNum;
}
public GifDrawable loadImage(final View viewParent,final int viewTag,final String imageUrl,final GifLoadCallback callback){
if (imageMap.containsKey(imageUrl)) {
GifDrawable drawable=imageMap.get(imageUrl);
return drawable;
}
// int index=imageUrl.lastIndexOf("/");
// index=index>=0?index:0;
// String filename=imageUrl.substring(index);
// final String filepath=path+filename+".0";
//
// final File mf=new File(filepath);
// if(mf.exists()){
// //File read to be added
// if(draw!=null){
// imageMap.put(imageUrl,draw);
// chackMapSize();
// return draw;
// }
// }
imageMap.put(imageUrl,null);
final Handler handler = new Handler () {

};
executor.execute(new Runnable() {

byte[] buff = new byte[512];
int rc = 0;
try {

swapStream.write(buff, 0, rc);
}
} catch (IOException e) {

chackMapSize();
}
else{

handler.sendMessage(message);
imageMap.remove(imageUrl);
}
// if(drawable!=null){

Run and see:
