本文使用ImageLoader下载网络图片
- 首先获得下载到了loadedImage
- 设置到创建快捷方式的Intent.EXTRA_SHORTCUT_ICON 这个是用来展示图标的
- 快捷方式需要一个 Intent.EXTRA_SHORTCUT_INTENT，可以传递参数给目标intent
创建桌面快捷方式之后
点击其中一个快捷方式后打开的界面
具体的代码实现方式
/**
* 创建团队快捷方式
* @param nickname
*/
public void createShortCut(final String nickname,final String imageUrl, final String id) {
//读取缓存团队小图
ImageLoader.getInstance().loadImage(imageUrl, new ImageLoadingListener() {
@Override
public void onLoadingCancelled(String arg0, View arg1) {
}
@Override
public void onLoadingStarted(String s, View view) {
}
@Override
public void onLoadingFailed(String s, View view, FailReason failReason) {
}
@Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
if(hasShortcut(mContext, nickname)) {
Toast.makeText(mContext, "团队\""+nickname + "\"已存在桌面快捷方式", Toast.LENGTH_SHORT).show();
} else {
Intent shortcutIntent = new Intent();
shortcutIntent.setAction("android.intent.action.gotogroup");
shortcutIntent.addCategory("android.intent.category.DEFAULT");
shortcutIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_DOCUMENT);
shortcutIntent.setFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
// shortcutIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
shortcutIntent.putExtra("groupidstr", id);
shortcutIntent.putExtra("groupnamestr", nickname);
shortcutIntent.putExtra("category", "grouphomepage");
shortcutIntent.putExtra("isfromshortcut", true);
if(Build.VERSION.SDK_INT >=Build.VERSION_CODES.O){
Bitmap resBit = null;
if (TextUtils.isEmpty(imageUrl)) {
// 快捷方式的图标
// resBit = createBitmap(
// BitmapFactory.decodeResource(getResources(), R.mipmap.group_head),
// BitmapFactory.decodeResource(getResources(), R.mipmap.ic_group_avar));
resBit = BitmapFactory.decodeResource(mContext.getResources(), R.mipmap.group_head);
} else {
//添加水印
// resBit = createBitmap(loadedImage,BitmapFactory.decodeResource(getResources(), R.mipmap.ic_group_avar));
resBit = loadedImage;
}
addShortCut(mContext, resBit, nickname, shortcutIntent, id);
} else {
Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
// 快捷方式名称
shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, nickname);
// 不允许重复创建（不一定有效）
shortcut.putExtra("duplicate", false);
if (TextUtils.isEmpty(imageUrl)) {
// 快捷方式的图标
// Parcelable iconResource = Intent.ShortcutIconResource.fromContext(mContext,
// R.mipmap.group_head);
// shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON, createBitmap(
BitmapFactory.decodeResource(mContext.getResources(), R.mipmap.group_head),
BitmapFactory.decodeResource(mContext.getResources(), R.mipmap.ic_group_avar)));
} else {
// shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON, loadedImage);
//添加水印
Bitmap resBit = BitmapFactory.decodeResource(mContext.getResources(), R.mipmap.ic_group_avar);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON, createBitmap(loadedImage, resBit));
}
mContext.sendBroadcast(shortcut);
Toast.makeText(mContext, "已将团队\"" + nickname + "\"添加至桌面", Toast.LENGTH_SHORT).show();
}
}
}
});
}
8.0以后的版本创建快捷方式发生变化
@RequiresApi(api = Build.VERSION_CODES.O)
public void addShortCut(Context context, Bitmap bitmap, String name, Intent shortcutIntent, String id) {
ShortcutManager shortcutManager = (ShortcutManager) context.getSystemService(Context.SHORTCUT_SERVICE);
if (shortcutManager.isRequestPinShortcutSupported()) {
//startActivity(shortcutIntent);
ShortcutInfo info = new ShortcutInfo.Builder(context, id)
.setIcon(Icon.createWithBitmap(bitmap))
.setShortLabel(name)
.setIntent(shortcutIntent)
.build();
//当添加快捷方式的确认弹框弹出来时，将被回调
PendingIntent shortcutCallbackIntent = PendingIntent.getBroadcast(context, 0, new Intent(context, MyBootReceiver.class), PendingIntent.FLAG_UPDATE_CURRENT);
shortcutManager.requestPinShortcut(info, shortcutCallbackIntent.getIntentSender());
}
}
图片合成
/**

* @param
* @return
*/
private Bitmap createBitmap( Bitmap src, Bitmap watermark ) {
if( src == null ) {
return null;
}
int w = src.getWidth();
int h = src.getHeight();
int ww = watermark.getWidth();
int wh = watermark.getHeight();
//新建矩形r1
RectF r1 = new RectF();
r1.left = 0;
r1.right = w;
r1.top = 0 ;
r1.bottom = h - 2;
Paint paint = new Paint();
paint.setAntiAlias(true);
//create the new blank bitmap
Bitmap newb = Bitmap.createBitmap( w, h, Bitmap.Config.ARGB_8888 );//创建一个新的和SRC长度宽度一样的位图
Canvas cv = new Canvas( newb );
cv.drawRoundRect(r1, (float) h / 5, (float) h / 5, paint);//圆角1/5
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
//draw src into

//draw watermark into

//save all clip

//store
cv.restore();//存储
return newb;
}
private static Bitmap small(Bitmap bitmap, float scale) {
Matrix matrix = new Matrix();
matrix.postScale(scale,scale); //长和宽放大缩小的比例
Bitmap resizeBmp = Bitmap.createBitmap(bitmap,0,0,bitmap.getWidth(),bitmap.getHeight(),matrix,true);
return resizeBmp;
}
判断是否已经存在快捷方式，部分手机可能会失效
public boolean hasShortcut(Activity activity, String shortcutName) {
try{
String url = "";
url = "content://" + getAuthorityFromPermission(activity, "com.android.launcher.permission.READ_SETTINGS") + "/favorites?notify=true";
ContentResolver resolver = activity.getContentResolver();
Cursor cursor = resolver.query(Uri.parse(url), new String[]{"title"}, "title=?", new String[]{shortcutName}, null);
if (cursor != null && cursor.moveToFirst()) {
cursor.close();
return true;
}
// return false;
return hasShortcut2(activity, shortcutName);
}catch (Exception e){
return false;
}
}
//魅族手机权限
public boolean hasShortcut2(Activity activity, String shortcutName) {
String url = "";
url = "content://" + getAuthorityFromPermission(activity, "com.meizu.flyme.launcher.permission.READ_SETTINGS") + "/favorites?notify=true";
ContentResolver resolver = activity.getContentResolver();
Cursor cursor = resolver.query(Uri.parse(url), new String[]{"title"}, "title=?", new String[]{shortcutName}, null);
if (cursor != null && cursor.moveToFirst()) {
cursor.close();
return true;
}
return false;
}
private String getAuthorityFromPermission(Context context, String permission) {
if (permission == null)
return null;
List<PackageInfo> packs = context.getPackageManager().getInstalledPackages(PackageManager.GET_PROVIDERS);
if (packs != null) {
for (PackageInfo pack : packs) {
// if(pack.packageName.contains("launcher")) {
ProviderInfo[] providers = pack.providers;
if (providers != null) {
for (ProviderInfo provider : providers) {
//使用正则去匹配launcher 信息
if (provider.name.contains("LauncherProvider")){
String valse = ".*launcher.*settings$";
Pattern pat = Pattern.compile(valse);
Matcher mat = pat.matcher(provider.authority);
if (mat.find()) {
return provider.authority;
}
}
if (permission.equals(provider.readPermission))
return provider.authority;
if (permission.equals(provider.writePermission))
return provider.authority;
}
}
// }
}
}
return null;
}
注意：需要手动打开app的创建快捷方式的权限
