我无法通过单击列表视图中的项目开始新活动。我希望它onItemClick
可以打开ApkInfoActivity
..实际上当我单击时没有任何反应。
protected void onItemClick(ListView l, View v, int position, long id, AdapterView<?> parent) {
super.onListItemClick(l, v, position, id);
final ApplicationInfo app = applist.get(position);
PackageInfo packageInfo = (PackageInfo) parent.getItemAtPosition(position);
AppDataActivity appData = (AppDataActivity) getApplicationContext();
appData.setPackageInfo(packageInfo);
Intent appInfo = new Intent(getApplicationContext(), ApkInfoActivity.class);
startActivity(appInfo);
}
我找不到问题..我该如何解决?
用 logcat 编辑:
