思路： 获得手机上应用列表，同时获得应用的图标、应用名、包名信息。 代码如下（简单的listview+获得应用列表信息，布局文件不给出）： public class InstallActivity extends AppCompatActivity {
ListView lView;
List<String> results = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_uninstall_warning);
lView = (ListView) findViewById(R.id.list_view);
PackageManager pm = this.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
for (ResolveInfo rInfo : list) {
results.add(rInfo.activityInfo.applicationInfo.loadLabel(pm).toString());
pm.getApplicationIcon(rInfo.activityInfo.applicationInfo);//获得应用的图标
pm.getApplicationLabel(rInfo.activityInfo.applicationInfo).toString();//获得应用名
String a = rInfo.activityInfo.applicationInfo.packageName;//获得应用包名
Log.e("InstallActivity","包名："+a);
}
lView.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, results));
}
}最主要的是pm.getApplicationIcon(rInfo.activityInfo.applicationInfo);//获得应用图标 pm.getApplicationLabel(rInfo.activityInfo.applicationInfo).toString();//获得应用名称 rInfo.activityInfo.applicationInfo.packageName;获得应用包名
