請幫助...我是新來的android開發...我有我的問題搜索，但沒有得到任何解決方案... 我也試過： Didn't understand it如何獲得安裝的應用程序的權限
我已經得到所有已安裝的應用程序的列表，所以現在我想表現出一個TextView每個應用程序的所有權限，當點擊它
列出所有已安裝的應用程序：
主要活動：
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView userInstalledApps = (ListView)findViewById(R.id.installed_app_list);
List<AppList> installedApps = getInstalledApps();
AppAdapter installedAppAdapter = new AppAdapter(MainActivity.this, installedApps);
userInstalledApps.setAdapter(installedAppAdapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private List<AppList> getInstalledApps() {
List<AppList> res = new ArrayList<AppList>();
List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
for (int i = 0; i < packs.size(); i++) {
PackageInfo p = packs.get(i);
if ((isSystemPackage(p) == false)) {
String appName = p.applicationInfo.loadLabel(getPackageManager()).toString();
Drawable icon = p.applicationInfo.loadIcon(getPackageManager());
res.add(new AppList(appName, icon));
}
}
return res;
}
private boolean isSystemPackage(PackageInfo pkgInfo) {
return ((pkgInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) ? true : false;
}
}
APPLIST類別：
public class AppList {
private String name;
Drawable icon;
public AppList(String name, Drawable icon) {
this.name = name;
this.icon = icon;
}
public String getName() {
return name;
}
public Drawable getIcon() {
return icon;
}
}
AppAdapter：
public class AppAdapter extends BaseAdapter {
private LayoutInflater layoutInflater;
private List<AppList> listStorage;
public AppAdapter(Context context, List<AppList> customizedListView) {
layoutInflater =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
listStorage = customizedListView;
}
@Override
public int getCount() {
return listStorage.size();
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder listViewHolder;
if(convertView == null){
listViewHolder = new ViewHolder();
convertView = layoutInflater.inflate(R.layout.installed_app_list, parent, false);
listViewHolder.textInListView = (TextView)convertView.findViewById(R.id.list_app_name);
listViewHolder.imageInListView = (ImageView)convertView.findViewById(R.id.app_icon);
convertView.setTag(listViewHolder);
}else{
listViewHolder = (ViewHolder)convertView.getTag();
}
listViewHolder.textInListView.setText(listStorage.get(position).getName());
listViewHolder.imageInListView.setImageDrawable(listStorage.get(position).getIcon());
return convertView;
}
static class ViewHolder{
TextView textInListView;
ImageView imageInListView;
}
}
activity_main.xml中
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#eceaea">
<ListView
android:id="@+id/installed_app_list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentTop="true"
android:scrollbars="none" />
</RelativeLayout>
installed_apps_list.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView

android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="16dp"
android:layout_marginTop="16dp"
android:paddingBottom="8dp"/>
<TextView

android:layout_marginTop="2dp"
android:text="@string/hello_world"/>
</RelativeLayout>
這是我做了什麼....我的意思是我得到的所有安裝的應用程序現在我想 每個應用點擊任何列出的應用程序時的權限....
你在清單採取必要的權限？ –
不，我沒有..... – Baadsha
你得到安裝包嗎？ –
