###1.应用程序信息的flags
1. int flags = packageInfo.applicationInfo.flags
2. 0000 0000 0000 0000 0000 0000 0000 0000 //int的32位每一位的0或者1表示一个boolean值
3. 适用于需要大量boolean变量的场景，提高效率
4. 具体代码
int flags = packInfo.applicationInfo.flags;
if ((flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
//系统应用
} else {
//用户应用
}
if ((flags & ApplicationInfo.FLAG_EXTERNAL_STORAGE) != 0) {
//安装在sd卡
} else {
//安装在手机内存
}
###2.应用的安装位置
<manifest
... SD卡 手机内存 手机内存
android:installLocation="preferExternal | internalOnly | auto"
/>
###3.如何区分显示系统应用和用户应用
1. 将“应用程序集合”拆分成“用户程序集合”和“系统程序集合”两个集合
2. 在getView方法中，根据position判断，该位置应该是用户程序还是系统程序，在从对应的集合中取出数据
3. 注意，当显示第二个集合的数据时，需要对position进行修正
###4.将标签加入到ListView的item中显示
1. 在getCount中计算出正确的个数：用户程序个数+系统程序个数+标签个数
2. 在getView中，根据position判断需要显示的四种类型：用户程序标签、用户程序、系统程序标签、系统程序，根据不同的类型返回不同的view
3. 注意，标签是插在列表的前面和中间，需要对position进行修正
###5.ListView的item具有多种布局
当我们在Adapter中调用方法getView的时候，如果整个列表中的Item View如果有多种类型布局，如：
我们继续使用convertView来将数据从新填充貌似不可行了，因为每次返回的convertView类型都不一样，无法重用。
Android在设计上的时候，也想到了这点。所以，在adapter中预留的两个方法。
public int getViewTypeCount(); //有多少种布局类型
public int getItemViewType(int position); //获取某个位置是哪种类型类型
只需要重写这两个方法，设置一下ItemViewType的个数和判断方法，Recycler就能有选择性的给出不同的convertView了。
private static final int TYPE_LABEL = 0;
private static final int TYPE_CONTENT = 1;
private class AppManagerAdapter extends BaseAdapter{
@Override
public int getViewTypeCount() {
return 2;
}
@Override
public int getItemViewType(int position) {
if(position == 0 || position == userAappInfos.size()+1){
return TYPE_LABEL;
}else{
return TYPE_CONTENT;
}
}
/**
* 返回listview里面有多少个条目
*/
@Override
public int getCount() {
//为什么要加两个1 ， 增加了两个textview的标签。整个listview条目的个数增加了。
return 1+userAappInfos.size()+1+systemAppInfos.size();
}
/**
* 显示每个条目的view对象
*/
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LabelViewHolder labelViewHolder = null;
ContentViewHolder contentViewHolder = null;
int type = getItemViewType(position);
if(convertView == null){
switch (type) {
case TYPE_LABEL:
convertView = new TextView(AppManagerActivity.this);
labelViewHolder = new LabelViewHolder();
labelViewHolder.tv_label = (TextView) convertView;
labelViewHolder.tv_label.setBackgroundColor(Color.GRAY);
convertView.setTag(labelViewHolder);
break;
case TYPE_CONTENT:
convertView = View.inflate(getApplicationContext(), R.layout.item_appinfo, null);

contentViewHolder.iv_appIcon = (ImageView) convertView.findViewById(R.id.iv_appicon);
contentViewHolder.tv_appName = (TextView) convertView.findViewById(R.id.tv_appName);
contentViewHolder.tv_apkSize = (TextView) convertView.findViewById(R.id.tv_apkSize);
contentViewHolder.iv_install_location = (ImageView) convertView.findViewById(R.id.iv_install_location);
convertView.setTag(contentViewHolder);
break;
}
}else{
switch (type) {

labelViewHolder = (LabelViewHolder) convertView.getTag();

case TYPE_CONTENT:
contentViewHolder = (ContentViewHolder) convertView.getTag();
break;
}
}
switch (type) {
case TYPE_LABEL:
if(position == 0){
labelViewHolder.tv_label.setText("用户程序："+userAappInfos.size());
}else{
labelViewHolder.tv_label.setText("系统程序："+systemAppInfos.size());
}
break;
case TYPE_CONTENT:
AppInfo appInfo;
if(position<=userAappInfos.size()){//用户程序
int newPosition = position - 1;//减去用户的标签textview占据的位置
appInfo = userAappInfos.get(newPosition);
}else {//系统程序
int newPosition = position - 1 - userAappInfos.size() - 1;
appInfo = systemAppInfos.get(newPosition);
}
contentViewHolder.iv_appIcon.setImageDrawable(appInfo.getAppIcon());
contentViewHolder.tv_appName.setText(appInfo.getAppName());
contentViewHolder.tv_apkSize.setText("程序大小："+Formatter.formatFileSize(getApplicationContext(), appInfo.getAppSize()));
if(appInfo.isInRom()){
contentViewHolder.iv_install_location.setImageResource(R.drawable.memory);
}else{
contentViewHolder.iv_install_location.setImageResource(R.drawable.sd);
}
break;
}
return convertView;
}
@Override

###6.ListView的OnScrollListener--滑动监听器
public static int SCROLL_STATE_IDLE = 0; //停止
public static int SCROLL_STATE_TOUCH_SCROLL = 1; //手指拖动
public static int SCROLL_STATE_FLING = 2; //惯性滑动
listView.setonScrollListener(new OnScrollListener() {
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
//滚动状态发生变化。0停止，1手指拖动，2惯性滑动
}
@Override
public void onScroll(AbsListView view, int firstVisibleItem,int visibleItemCount, int totalItemCount) {
//当listview正在滚动的时候调用的方法
//firstVisibleItem：第一个显示的Item的位置
//visibleItemCount：可显示的Item的总数
//totalItemCount：Item的总数
}
});
###7.PopupWindow的使用
//创建，指定显示的View和宽高
PopupWindow ppw = new PopupWindow(View contentView, int width, int height);
//显示，parent并不是指要把contentView 添加到parent上，而是要获取token
ppw. showAtLocation(View parent, int gravity, int x, int y);
//关闭
ppw. dismiss();
###8.PopupWindow使用注意事项
1.在show之前dismiss掉之前创建的，避免重复显示
2.在Activity的onDestory()的时候dismiss，避免窗体泄漏
###9.获取View在Window中的位置
int[] location = new int[2];
view.getLocationInWindow(location);
Location[0]： x坐标
Location[1]： y坐标
获取View在父View中的位置
view.getX();
view.getY();
###10.PopupWindow不显示动画的原因
1.手机中设置了动画关闭
2.PopupWindow没有设置背景
注：PopupWindow要设置背景和获取焦点，才能有点击弹框外消失的效果
###1.卸载应用的Intent
卸载请求
Intent intent = new Intent();
intent.setAction("android.intent.action.DELETE");
intent.addCategory("android.intent.category.DEFAULT");
intent.setData(Uri.parse("package:"+clickedAppInfo.getPackName()));
startActivity(intent);
安装请求
Intent intent = new Intent();
intent.setAction("android.intent.action.VIEW");
intent.addCategory("android.intent.category.DEFAULT");
intent.setDataAndType(
Uri.fromFile(new File(apk_path)),
"application/vnd.android.package-archive");
startActivity(intent);
###2.接收卸载应用程序的广播
AppUninstallReceiver receiver = new AppUninstallReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
filter.addDataScheme("package");
registerReceiver(receiver, filter);
* **相关广播**
* ACTION\_PACKAGE\_ADDED 一个新应用包已经安装在设备上，数据包括包名（最新安装的包程序不能接收到这个广播，（当前正在安装的程序不能接收这个广播））
* ACTION\_PACKAGE\_REPLACED 一个新版本的应用安装到设备，替换之前已经存在的版本
* ACTION\_PACKAGE\_REMOVED 一个已存在的应用程序包已经从设备上移除，包括包名（正在被卸载的包程序不能接收到这个广播）
###3.遍历集合时如何删除数据
方法一：高级for循环，记录要删除的数据，遍历后再删除
AppInfo deleteAppInfo = null;
//更新ui界面
for(AppInfo appinfo: userAppInfos){
if(appinfo.getPackName().equals(packname)){
deleteAppInfo = appinfo;
}
}
if(deleteAppInfo!=null){
userAppInfos.remove(deleteAppInfo);
}
方法二：使用迭代器进行遍历，可在遍历中删除
Iterator<AppInfo> iterator = userAppInfos.iterator();
while(iterator.hasNext()){
AppInfo appinfo = iterator.next();
if (appinfo.getPackName().equals(packname)) {
iterator.remove();
}
}
方法三：使用普通for循环倒叙，可在遍历中删除。注意：如不采用倒叙，会遍历不全
for (int i = userAppInfos.size() - 1; i >= 0; i--) {
AppInfo appinfo = userAppInfos.get(i);
if (appinfo.getPackName().equals(packname)) {
userAppInfos.remove(i);
break;
}
}
###4.启动一个应用程序
PackageManager pm = getPackageManager();
Intent intent = pm.getLaunchIntentForPackage(clickedAppInfo.getPackName());
if(intent!=null){
startActivity(intent);
}else{
Toast.makeText(this, "对不起，该应用无法被开启", 0).show();
}
###5.分享
Intent intent = new Intent();
intent.setAction("android.intent.action.SEND");
intent.addCategory("android.intent.category.DEFAULT");
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "推荐你使用一款软件："+clickedAppInfo.getAppName()+"，真的很好用哦");
startActivity(intent);
###6.详细信息
Intent intent = new Intent("android.settings.APPLICATION_DETAILS_SETTINGS");
intent.addCategory(Intent.CATEGORY_DEFAULT);
intent.setData(Uri.parse("package:"+clickedAppInfo.getPackName()));
startActivity(intent);
