Swipe Refresh in Textview

Question

I wonder if there is any way to implement a refresh Swipe in android studio to update only a textview when triggering? I’m using android studio, Activity has only a two text view at the top static that doesn’t change, six Buttons, and finally a textview that changes over time.

Answer 1

In your class, use the method setOnRefreshListener by changing the content of your TextView. That’s all:

SwipeRefreshLayout swipeLayout = (SwipeRefreshLayout) findViewById(R.id.swipe);
swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
    @Override
    public void onRefresh() {
       meuTextView.setText("Aqui o novo texto ao usar o swipe refresh");
       swipeLayout.setRefreshing(false);
    }
});

XML

Your .xml may be something along those lines:

.

.
<!-- aqui suas outras views se houver-->

<android.support.v4.widget.SwipeRefreshLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/swipe"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

   <!-- aqui suas outras views se houver-->

    <TextView
        android:id="@+id/meuTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Jon Snow"
        android:textSize="40dp"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />


    <!-- aqui suas outras views se houver-->

</android.support.v4.widget.SwipeRefreshLayout>

Answer 2

swipeLayout.setOnRefreshListener(
    new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            updateMessage("Hi, Jarbas");
        }
    }
);

// ...
private void updateMessage(String msg) {
    textMessage.setText(msg);
    swipeLayout.setRefreshing(false);
}

This will update your text TextView and also stop updating Swipe if you leave the method setRefreshing as true or not to inform that it should be false, the Swipe layout continue with the loading animation.
