Usage

Step 1:Add the dependency:

open the build.gradle file of your module, at the dependencies function add the below code:

    compile 'com.lvleo:data-loading-layout:0.1.1'

Step 2:Add the view to your layout.xml file:

<com.lvleo.dataloadinglayout.DataLoadingLayout        android:id="@+id/loading_layout"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_below="@id/layout_buttons"        android:background="@android:color/darker_gray"        app:loadingBarColor="@android:color/holo_purple"        app:statusText="暂无数据"        app:statusTextColor="@android:color/black"        app:statusTextSize="16sp"        />

Step 3: The activity implements DataLoadingLayout.OnViewTouchListener, after init the view setDataView(view) and setOnMyViewTouchListener(this),final Override the onTouchUp() function. like this:

public class MainActivity extends AppCompatActivity implements DataLoadingLayout.OnViewTouchListener {    private static final String TAG = MainActivity.class.getSimpleName();    private Button btnNoData, btnDataLoadingSuccess, btnDataLoadingError;    private TextView txtResult;    private DataLoadingLayout mLoadingLayout;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        btnNoData = (Button) findViewById(R.id.btn_data_empty);        btnDataLoadingSuccess = (Button) findViewById(R.id.btn_data_success);        btnDataLoadingError = (Button) findViewById(R.id.btn_data_error);        txtResult = (TextView) findViewById(R.id.txt_result);        mLoadingLayout = (DataLoadingLayout) findViewById(R.id.loading_layout);        mLoadingLayout.setDataView(txtResult);        mLoadingLayout.setOnMyViewTouchListener(this);        btnNoData.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                getData("http://api.map.baidu.com/telematics/v3/weather?location=");            }        });        btnDataLoadingSuccess.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                getData("http://api.map.baidu.com/telematics/v3/weather?location=无锡");            }        });        btnDataLoadingError.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                getData("http://api.map.baidu.com/telematics/v3/weathersssss?location=无锡");            }        });        mLoadingLayout.loadSuccess("Demo 演示");    }    @Override    public void onTouchUp() {        // if data load Error, can get data again by touch the view        getData("http://api.map.baidu.com/telematics/v3/weather?location=无锡");    }    private void getData(String subUrl) {        mLoadingLayout.loading();        String url = subUrl + "&output=json&ak=6gYxFLrG9vipiq1bkQLnHhUH&" +                "mcode=4C:45:2B:FC:13:89:0F:76:88:A8:D3:9F:69:F6:51:9C:BC:F6:9E:65;baidumapsdk.demo";        AsyncHttpClient client = new AsyncHttpClient();        client.setTimeout(20 * 1000);        client.setConnectTimeout(20 * 1000);        client.setResponseTimeout(20 * 1000);        client.setMaxRetriesAndTimeout(3, 20 * 1000);        client.allowRetryExceptionClass(SocketTimeoutException.class);        client.allowRetryExceptionClass(ConnectTimeoutException.class);        client.get(url, new JsonHttpResponseHandler() {            @Override            public void onSuccess(int statusCode, Header[] headers, JSONObject response) {                super.onSuccess(statusCode, headers, response);                Log.i(TAG, "onSuccess: response==" + response);                if (response.optInt("error") == 0) {                    mLoadingLayout.loadSuccess();                    JSONObject object = response.optJSONArray("results").optJSONObject(0).                            optJSONArray("weather_data").optJSONObject(0);                    String weather = "今日天气\r\n" + object.optString("date") + "\r\n 温度：" +                            object.optString("temperature") + "\r\n 风向：" + object.optString("wind");                    txtResult.setText(weather);                } else {                    mLoadingLayout.loadSuccess("暂无数据,\n 点击屏幕 重新加载 ");                }            }            @Override            public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {                super.onFailure(statusCode, headers, responseString, throwable);                mLoadingLayout.loadError("服务器连接失败,\n 点击屏幕 重新加载");            }        });    }}
