如何从一个微调框显示的列表中得到一个Android应用程序的UID值？应用程序、列表中、Android、UID
我开发一个小的应用程序，它显示已安装的应用程序，在微调的列表。只有应用程序名称显示为微调值。每当我从微调选择一个应用程序，我需要找回所选应用程序的UID。我怎样才能实现的功能？
I am developing a small application which displays the installed application as a list in a spinner. Only the application name is displayed as spinner values. Whenever I select an application from spinner I need to retrieve the UID of the selected application. How can I implement the function?
以下是我的code从微调
The following is my code for getting the application name from the spinner
appspinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View arg1,
int app_pos, long app_id) {
// TODO Auto-generated method stub
String app_selected=parent.getItemAtPosition(app_pos).toString();
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
return;
}
});
使用PackageManager类和使用PackageInfo类我正在应用程序的名称的安装的应用程序被存储在一个列表中。
The installed application is stored in a list using the PackageManager class and using PackageInfo class I am getting the name of the application.
推荐答案
您需要使用 PackageManager 来获取有关的任何应用程序，你在列表中选择包信息。我没有用微调，但我敢肯定，因为它在做它应该工作一样我的的ListView 。
You will need to use PackageManager to get the package information about whatever app you select in the list. I haven't done this with a Spinner but i'm sure it should work the same as it did in my ListView.
appspinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View arg1,
int app_pos, long app_id) {
// TODO Auto-generated method stub
String app_selected=parent.getItemAtPosition(app_pos).toString();
final PackageManager pm = getPackageManager();
//get a list of installed apps.
List<ApplicationInfo> packages = pm.getInstalledApplications(
PackageManager.GET_META_DATA);
int UID;
//loop through the list of installed packages and see if the selected
//app is in the list
for (ApplicationInfo packageInfo : packages) {
if(packageInfo.packageName.equals(app_selected)){
//get the UID for the selected app
UID = packageInfo.uid;
break; //found a match, don't need to search anymore
}
}
//Do whatever with the UID
Log.i("Check UID", "UID is: " + UID);
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
return;
}
});
您可能想看看的packageName 返回的packageName ，所以你可以尝试与任何选择与之相匹配
You might want to see how packageName returns the packageName so you can try to match it with whatever was selected.
希望这点你在正确的方向，并帮助你的。祝您好运。
