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:0.1.2'###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="????"
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);
//
TextView textView = mLoadingLayout.getTextViewStatus();
//
textView.setTextColor(Color.RED);
//
textView.setCompoundDrawablesWithIntrinsicBounds(0, R.mipmap.ic_sad, 0, 0);
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=??");
}
}
);
btnDataLoadingError.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getData("http://api.map.baidu.com/telematics/v3/weathersssss?location=??");
}
}
);
txtResult.setText("???????????????");
mLoadingLayout.setStatusTopIcon(R.mipmap.ic_sad);
}
@Override
public void onTouchUp() {
// if data load Error or data is empty, can get data again by touch the view
getData("http://api.map.baidu.com/telematics/v3/weather?location=??");
}
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 = "????\r\n" + object.optString("date") + "\r\n ???" +
object.optString("temperature") + "\r\n ???" + object.optString("wind");
txtResult.setText(weather);
}
else {
mLoadingLayout.loadSuccess("????\n???? ???? ");
}
}
@Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
super.onFailure(statusCode, headers, responseString, throwable);
mLoadingLayout.loadError("???????\n???? ????");
}
}
);
}
}
