I am fetching data from the web using volley and displaying the result in TextViews and an NetworkImageView.
I have succeeded in saving and restoring the states of the textviews but I ran into a problem with the NetworkImageView.
FruitDetails
public class FruitDetails extends AppCompatActivity {
private final String TAG = "FruitDetails";
TextView fruitTitle, fruitContent;
NetworkImageView authorImg;
ImageLoader AuthImgLoader;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fruit_details);
fruitTitle = (TextView) findViewById(R.id.dfruit_title);
fruitContent = (TextView) findViewById(R.id.dfruit_content);
authorImg = (NetworkImageView) findViewById(R.id.author_img);
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
}
if (savedInstanceState != null) {
fruitTitle.setText(savedInstanceState.getString("fruitTitle"));
fruitContent.setText(savedInstanceState.getString("fruitContent"));
} else {
loadFruit();
}
}
private void loadFruit() {
Log.d(TAG, "loadFruit called");
final ProgressBar progressBar;
progressBar = (ProgressBar) findViewById(R.id.progress_circle);
progressBar.setVisibility(View.VISIBLE);
int news_id = getIntent().getIntExtra("FruitId", -1);
Log.d(TAG, "You clicked fruit id " + fruits_id);
final JsonObjectRequest jsonObjReq = new JsonObjectRequest( DetailConfig.GET_DURL + news_id, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.d("Debug", response.toString());
//Dismissing progressbar;
if (progressBar != null) {
progressBar.setVisibility(View.GONE);
}
//Calling method to parse json array
parseFruit(response);
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("", "Error: " + error.getMessage());
}
});
//Creating request queue
RequestQueue requestQueue = Volley.newRequestQueue(this);
//Adding request to queue
requestQueue.add(jsonObjReq);
}
//This method will parse json data of fruit
private void parseFruit(JSONObject jsonObject) {
Log.d(TAG, "Parsing fruit array");
try {
String title = jsonObject.getString(DetailConfig.TAG_DFRUIT_TITLE);
fruitTitle.setText(Html.fromHtml(title));
JSONObject pAuthor = jsonObject.getJSONObject("author");
String authorimg = pAuthor.getString("avatar");
AuthImgLoader = VolleyRequest.getInstance(getApplicationContext()).getImageLoader();
AuthImgLoader.get(authorimg, ImageLoader.getImageListener(authorImg, R.drawable.ic_author, R.drawable.ic_author));
authorImg.setImageUrl(authorimg, AuthImgLoader);
String content = jsonObject.getString(DetailConfig.TAG_DFRUIT_CONTENT);
fruitContent.setText(Html.fromHtml(content));
} catch (JSONException w) {
w.printStackTrace();
}
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putString("fruitTitle", fruitTitle.getText().toString());
outState.putString("fruitContent", fruitContent.getText().toString());
//outState.putInt("authorImg", authorImg // I got into problem here
}
}
While I couldn't restore that of the NetworkImageView at all, the fruitContent has an anomaly: when I rotate the screen, the styling (e.g bold) of the text is lost i.e it's returned to normal.
Edit I discovered that the reason why the styling is lost is because I was setting and getting it as string; is there anyway I can use Parcelables?
