Issues when relative layout implement swipe-to-refresh layout

Question

I'm currently attempting to implement swipe-to-refresh layout into relative layout, but it is extremely insensitive and unstable. When I pull down the screen, it usually either doesn't refresh or it refreshes without progress bar.

<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="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.miaor.tutorialweather.MainActivity"
android:id="@+id/refreshLayout"
android:background="#fe970b">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</RelativeLayout>

public class MainActivity extends AppCompatActivity{

public static final String TAG = MainActivity.class.getSimpleName();
@BindView(R.id.TimeString) TextView mTimeLabel;
@BindView(R.id.TemperatureLabel) TextView mTemperatureLabel;
@BindView(R.id.HumidityValue) TextView mHumidityValue;
@BindView(R.id.rainingChanceValue) TextView mChance;
@BindView(R.id.weatherIcon) ImageView mWeatherIcon;
@BindView(R.id.SummaryText) TextView mSummaryText;
@BindView(R.id.refreshLayout) SwipeRefreshLayout mSwipeRefreshLayout;

///why do we make a new variable of CurrentWeather
private CurrentWeather mCurrentWeather;
private String apiKey = "6b9448b8e21c2abe2fb623b25554a77c";
private double latitude = 31.230708;
private double longitude = 121.472916;
private String forecastUrl = "https://api.forecast.io/forecast/" + apiKey +
        "/" + latitude + "," + longitude;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);

    ///implement swipe-to-refresh feature
    mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            Log.i(TAG, "onRefresh is working");
            getForecast();
        }
    });

    getForecast();

    Log.d(TAG, "Main UI code is running!");
}

You can't implement SwipeToRefreshLayout with RelativeLayout as its child. You need to have a scrollable view as its only child. e.g. Listview, RecyclerView, ScrollView. That is the reason why it is not working as expected for you.

That is not the right position.

You need type like this:

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/your_id"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        YOUR RELATIVE LAYOUT HERE

    </ScrollView>

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

Your code looks fine, it's weird that it's not working correctly... Maybe it's because of the ButterKnife library? I don't think that's the problem, but it will be worth the shot to get views manually to see if that's the problem

Then, if you need the loading animation to appear/hide you can use mSwipeRefreshLayout.setRefreshing(boolean);

For example in my app I attach the listener first (as you did in your example) and then I use the following code to show the loading animation while I fetch the data.

// Show loading while fetching the first set of data
mainSwipeRefreshLayout.post(new Runnable() {
    @Override
    public void run() {
        mainSwipeRefreshLayout.setRefreshing(true);
    }
});

In my fetchData() method I use the following line to hide the animation again when it finishes fetching the data.

// On load complete stop refresh animation
mainSwipeRefreshLayout.setRefreshing(false);

Hope this helps! Andres.
