I am working on an Android app (API 15 and below). In my UI I have a TextView element that I would like people to be able to select and copy from. Here is what my element looks like:
<LinearLayout android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="20dp" /> <TextView android:id="@+id/chat_info" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="0" android:padding="8dp" /> <TextView android:id="@+id/chat_message" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:layout_margin="2dp" android:padding="8dp" android:textSize="18sp" android:gravity="right" android:textColor="@color/BLACK" android:textIsSelectable="true"/> </LinearLayout> This TextView sits within a ListView that is populated with a SimpleCursorAdapter. This ListView looks like this:
<ListView android:id="@+id/chat_text_display" android:layout_width="match_parente" android:layout_height="0dp" android:layout_weight="1" android:layout_marginTop="2dp" android:layout_marginRight="2dp" android:layout_marginBottom="2dp" android:layout_marginLeft="2dp" android:padding="5dp" android:background="@color/WHITE" android:divider="@null" android:divider_height="0dp" android:stackFromBottom="true" android:transcriptMode="alwaysScroll"/> Whenever I try to single-click the text in chat_info or chat_message, nothing happens. However, whenever I try to double-click the text:
- my entire UI shifts down
- a "toolbar" shows up at the top of the screen
- the "toolbar" immediately goes away and my display shifts back up
In the "toolbar" this is what I see:

It looks like it is the copy dialog, but it goes away immediately.
All I am wanting to do is select the text in chat_info or chat_message so I can copy and paste the text elsewhere.
Any ideas?

Single click is expected. Android doesn't hilight on single click.
You're entering the action mode for copy paste. An action mode is a state of an activity where the toolbar switches out for a context aware set of commands (in this case copy/paste commands). It seems like you're entering it and then immediately exiting it, possibly because you're losing focus to another element.

There are a lot of typing errors in your xml ;O)
I would not use android:textIsSelectable="true"
This code copies automatically the data to clipboard on every user click.
I would do it like this (tested code on API19, easy enough to lower API):
//some test data static final String[] FRUITS = new String[] { "Apple", "Avocado", "Banana", "Blueberry", "Coconut", "Durian", "Guava", "Kiwifruit", "Jackfruit", "Mango", "Olive", "Pear", "Sugar-apple" }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); m_context = getApplicationContext(); setContentView(R.layout.shadow); ListView listView = (ListView) findViewById(R.id.chat_text_display); ArrayList<ChatRow> chat_list = new ArrayList<ChatRow>(); for(int i = 0 ;i<FRUITS.length;i++) { chat_list.add( new ChatRow(FRUITS[i]+"(chat_info)",FRUITS[i]+"(chat_message)")); } final ChatArrayAdapter chatArryAdapter = new ChatArrayAdapter(m_context, chat_list); listView.setAdapter(chatArryAdapter); } //================================================== public class ChatRow { private String name1 = "" ; private String name2 = "" ; //constructor public ChatRow( String name1, String name2 ) { this.name1 = name1; this.name2 = name2; } //setters and getters //-------------------------------------------------------------------------------- public String getName1() { return name1 ; } //-------------------------------------------------------------------------------- public void setName1(String name) { this.name1 = name ; } //-------------------------------------------------------------------------------- public String getName2() { return name2 ; } //-------------------------------------------------------------------------------- public void setName2(String name) { this.name2 = name ; } //-------------------------------------------------------------------------------- }//class ChatRow //================================================== public class ChatArrayAdapter extends ArrayAdapter<ChatRow> { private final Context context; //-------------------------------------------------------------------------------- //constructor public ChatArrayAdapter(Context context, ArrayList<ChatRow> rowList) { super(context, R.layout.achievements_item, R.id.chat_info, rowList); this.context = context; }//ChatArrayAdapter constructor //-------------------------------------------------------------------------------- @Override public View getView(int position, View convertView, ViewGroup parent) { // CBRow to display final ChatRow row = (ChatRow) this.getItem( position ); LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View rowView = inflater.inflate(R.layout.achievements_item, parent, false); TextView textView1 = (TextView) rowView.findViewById(R.id.chat_info); TextView textView2 = (TextView) rowView.findViewById(R.id.chat_message); textView1.setText(row.getName1()); textView2.setText(row.getName2()); textView1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Toast.makeText(m_context, "clicked first field:" + row.name1, Toast.LENGTH_SHORT).show(); } }); textView2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Toast.makeText(m_context, "clicked second field" + row.name2 + ", **copied to clipboard**", Toast.LENGTH_SHORT).show(); ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); ClipData clip = ClipData.newPlainText(row.name1, row.name2); clipboard.setPrimaryClip(clip); } }); return rowView; }//getView }//class ChatArrayAdapter //==================================================
