I tried to implement Pull to Refresh in my app.
I wrapped my xml code with android.support.v4.widget.SwipeRefreshLayout and it's working, but the GUI doesn't look good.
When I pull down, I should see the regular animated circle icon with my defined colors, right?, but I see it as a blank circle and not a turning one with colors as it should.
Furthermore, I can't "play" with it and even hold it for a while after I pull it, it goes down for one second (do what it does) and then disappears.
I think it's because I'm not using ListView but LinearLayout instead.
What do you think?
Code:
XML:
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/swipe">
<LinearLayout
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:orientation="vertical"
android:layout_width="match_parent"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:background="#7B68EE"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".HomeActivity">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/loin"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="@string/welcome"
android:textColor="#B0C4DE"
android:id="@+id/welcomeBackID"
android:layout_alignParentTop="true"
android:layout_alignRight="@+id/webViewCurren"
android:layout_alignEnd="@+id/webViewCurren" />
....
</android.support.v4.widget.SwipeRefreshLayout>
Java:
public class HomeActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener {
SwipeRefreshLayout mSwipeRefreshLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe);
mSwipeRefreshLayout.setColorSchemeResources(android.R.color.holo_green_light,
android.R.color.holo_blue_bright,
android.R.color.holo_orange_light,
android.R.color.holo_red_light);
mSwipeRefreshLayout.setOnRefreshListener(this);
@Override
public void onRefresh() {
Toast.makeText(this, "Refresh", Toast.LENGTH_SHORT).show();
sharedPrefEditor.putString("coordinateX", "34.7");
sharedPrefEditor.putString("coordinateY", "32.5");
sharedPrefEditor.putString("saved", "false");
sharedPrefEditor.commit();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
mSwipeRefreshLayout.setRefreshing(false);
}
}, 3000);
}
}
