Gboard键盘：数值inputType在ListView中的EditText上不起作用

Question

I am using default Android Gboard keyboard . But there is an issue when I am using inputType="number" on the EditText . The keyboard shown but type values not display in EditText , also not getting any type value in TextWatcher.

The EditText in the ListView element looks like the following:

<EditText
    android:id="@+id/editTextChecked"
    android:layout_width="150dp"
    android:layout_height="60dp"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_gravity="center"
    android:gravity="center"      
    android:inputType="number"
    android:textColor="#000000" />

The ListView is defined as:

<ListView
    android:id="@+id/listViewDialog"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@+id/bottom"
    android:layout_below="@+id/editTextSearch"
    android:background="@android:color/white"
    android:divider="@android:color/darker_gray"
    android:dividerHeight="1dp" />

This is my TextWather Code :-

 holder.etCheck.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            Log.e("text",""+s.toString());
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });

The thing with TextWatcher is that it doesn't work so well with ListView s. You have to define your own custom TextWatcher like this:

private class MyCustomEditTextListener implements TextWatcher {
    private int position;

    public void updatePosition(int position) {
        this.position = position;
    }

    @Override
    public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3) {
        // do your operations here.
    }

    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i2, int i3) {
    }

    @Override
    public void afterTextChanged(Editable editable) {
        Logger.e(TAG, "After" + editable.toString());
    }      
}

and inside getView() do this:

((Viewholder) holder).myCustomEditTextListener.updatePosition(position);

Finally inside your viewHolder initialise your EditText and add the custom TextWatcher to it.
