Android:启动onListViewItem上的新活动

Question

我有一个包含基本Listview的Activity.功能如下:

单击列表视图项 - >获取列表视图项名称 - >按意图传递名称并开始新活动.

除了新活动的开始之外,一切正常.它只是没有响应,我不明白为什么.我真的很感激一双额外的眼睛来看看这个.

listView = getListView();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, foodNames);
listView.setAdapter(adapter);

listView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView parentView, View childView, int position, long id) {

        TextView tv  = (TextView) listView.getSelectedItem();
        String value = tv.getText().toString();

        Log.v("DEBUG","Name of item clicked" + value);

        Intent intent = new Intent(childView.getContext(), FoodItemActivity.class);
        intent.putExtra("FoodName", value );
        startActivity(intent);

    }

    public void onNothingSelected(AdapterView parentView) {
    }
});

Answer 1

我觉得你错过了一线

startActivity(intent);
