回答1:
try this to get the focus: View.getFocus();
回答2:
Android doesn't allow to select list items that have focusable elements (buttons). Modify the button's xml attribute to:
android:focusable="false"
It should still be clickable, just won't gain focus...
回答3:
I had the same issue with a ListView which contained only a RadioButton:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<RadioButton
android:id="@+id/userNameRadioButton"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
I used the RadioButton in each row to display the default item selection, to make ListView handle clicks I had to use:
radioButton.setFocusableInTouchMode(false);
radioButton.setFocusable(false);
or in the XML-file:
android:focusable="false"
android:focusableInTouchMode="false"
So it is a focus related issue... With the above modifiers the focus is directed to ListView on click.

This answer here worked for me: https://stackoverflow.com/a/16536355/5112161
Mainly he ADDED in the LinearLayout or RelativeLayout the following:
android:descendantFocusability="blocksDescendants"
You also need to REMOVE from all your xml the following:
android:focusable="false"
android:focusable="true"
android:clickable="true"
android:clickable="false"

I wanted to add a comment to rupps answer, but I do not have enough reputation.
If you are using a custom adapter extending the ArrayAdapter you can overwrite with areAllItemsEnabled() and isEnabled(int position) in your class:
@Override
public boolean areAllItemsEnabled() {
return true;
}
@Override
public boolean isEnabled(int position) {
return true;
}
The above fixed my non clickable list view. Maybe this comment also helps others as "android list not clickable" search term is quite high in Google.
回答6:
Consider making the text value selectable by specifying android:textIsSelectable="true"
Don't listen to Google. In the rows' layout, set
textIsSelectable="false"
Thank you Lint (not!)
回答7:
List view items are clickable. To use it, you have to set item click listener on your list view. Then it will work.
回答8:
I'm pretty late but discovered something I think it's interesting about this:
if your adapter descends from ArrayAdapter, as much as I have tried, onItemClickListener is not called.
However, if your adapter descends from BaseAdapter (so you have to implement getCount() and getItem(), trivial for an array) it IS always called.
回答9:
I was using a view and button inside the list view so I have used:
android:focusable="false"
for <button> and <view> ...
After that I used following code for my list view and it worked
// Attach the adapter to a ListView
ListView listView = (ListView) findViewById(R.id.shipping_item_list);
listView.setAdapter(adapter);
listView.setOnItemClickListener(listPairedClickItem);
private AdapterView.OnItemClickListener listPairedClickItem = new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Toast.makeText(getBaseContext(), "Item ", Toast.LENGTH_LONG).show();
}
};
回答10:
For me, the problem was that my items within my ListView had clickable set to true.
回答11:
set android:clickable="false" android:focusable="fasle"
