I found TextView in RecyclerView can select first time ,but when ViewHolder was recycled or adapter notifyDataSetChanged,all text view will can't be selected.
And I found this solution was working for me.
yourTextView.setText("your text");
yourTextView.setTextIsSelectable(false);
yourTextView.measure(-1, -1);//you can specific other values.
yourTextView.setTextIsSelectable(true);
Why do this? because I have debugged and found some logic in android source code:
TextView.java:
public void setTextIsSelectable(boolean selectable) {
if (!selectable && mEditor == null) return; // false is default value with no edit data
createEditorIfNeeded();
if (mEditor.mTextIsSelectable == selectable) return;
mEditor.mTextIsSelectable = selectable;
setFocusableInTouchMode(selectable);
setFocusable(FOCUSABLE_AUTO);
setClickable(selectable);
setLongClickable(selectable);
// mInputType should already be EditorInfo.TYPE_NULL and mInput should be null
setMovementMethod(selectable ? ArrowKeyMovementMethod.getInstance() : null);
setText(mText, selectable ? BufferType.SPANNABLE : BufferType.NORMAL);
// Called by setText above, but safer in case of future code changes
mEditor.prepareCursorControllers();
}
Editor.java
void prepareCursorControllers() {
boolean windowSupportsHandles = false;
ViewGroup.LayoutParams params = mTextView.getRootView().getLayoutParams();
if (params instanceof WindowManager.LayoutParams) {
WindowManager.LayoutParams windowParams = (WindowManager.LayoutParams) params;
windowSupportsHandles = windowParams.type < WindowManager.LayoutParams.FIRST_SUB_WINDOW
|| windowParams.type > WindowManager.LayoutParams.LAST_SUB_WINDOW;
}
boolean enabled = windowSupportsHandles && mTextView.getLayout() != null;
mInsertionControllerEnabled = enabled && isCursorVisible();
**mSelectionControllerEnabled = enabled && mTextView.textCanBeSelected();**
if (!mInsertionControllerEnabled) {
hideInsertionPointCursorController();
if (mInsertionPointCursorController != null) {
mInsertionPointCursorController.onDetached();
mInsertionPointCursorController = null;
}
}
if (!mSelectionControllerEnabled) {
stopTextActionMode();
if (mSelectionModifierCursorController != null) {
mSelectionModifierCursorController.onDetached();
mSelectionModifierCursorController = null;
}
}
}
---> TextView.java
/**
* Test based on the <i>intrinsic</i> charateristics of the TextView.
* The text must be spannable and the movement method must allow for arbitary selection.
*
* See also {@link #canSelectText()}.
*/
boolean textCanBeSelected() {
// prepareCursorController() relies on this method.
// If you change this condition, make sure prepareCursorController is called anywhere
// the value of this condition might be changed.
if (mMovement == null || !mMovement.canSelectArbitrarily()) return false;
return isTextEditable()
|| (isTextSelectable() && mText instanceof Spannable && isEnabled());
}
you can debug in Emulator and trace this code.
