I'm building an Android TV app for which I've rewritten the loadRows() method as such:
private void loadRows(String[] CATEGORY_LIST) {
mRowsAdapter = new ArrayObjectAdapter(new ListRowPresenter());
int i;
for (i = 0; i < NUM_ROWS; i++) {
ArrayObjectAdapter listRowAdapter = new ArrayObjectAdapter(new ListRowPresenter());
HeaderItem header = new HeaderItem(i, CATEGORY_LIST[i]);
mRowsAdapter.add(new ListRow(header, listRowAdapter));
}
setAdapter(mRowsAdapter);
}
My problem is that the CATEGORY_LIST is being drawn twice: once when the app is launched, and once on a right arrow press.
When it is drawn on the right arrow press, the spaces between the items are a little bit bigger, so I assume that is a "feature" from ArrayObjectAdapter.
HeaderItem header1 = new HeaderItem(1, getString(R.string.pontos_title));
ArrayObjectAdapter listRowAdapter1 = new ArrayObjectAdapter(cardPresenter);
for (int z = 0; z < pontos.size() ; z++) {
listRowAdapter1.add(pontos.get(z));
}
mRowsAdapter.add(new ListRow(header1,listRowAdapter1));
ObjectAdapter mAdapter = getAdapter();
mAdapter.notifyItemRangeChanged(1, NewObjects.size()); //Line 1
If you want to update the item on the same line use, but remove first.
mRowsAdapter.removeItems(1, LastedObjects.size());// Line 1

I am displaying multiple rows in one header and there is 5 more categories like drama and I am doing the same job for them. My question is when I set the adapter categories displaying randomly.(assuming of request speed).For example I want the display Drama on the first line always. I gave them id of adapter's constructor but didn't work out. Code :
if (response.body().getItems().size() > 0) {
Log.d("Drama",""+response.body().getItems().size());
List<MovieItem> newMovieItems = response.body().getItems();
HeaderItem liveHeader = new HeaderItem("Drama");
LiveChannelPresenter liveChannelPresenter = new LiveChannelPresenter();
ArrayObjectAdapter liveRowAdapter = new ArrayObjectAdapter(liveChannelPresenter);
for (int i = 0; i < newMovieItems.size(); i++) {
movieItem2 = response.body().getItems().get(i);
liveRowAdapter.add(movieItem2);
}
mRowsAdapter.add(new ListRow(0,liveHeader,liveRowAdapter));
}
}
if (response.body().getItems().size() > 0) {
Log.d("Drama",""+response.body().getItems().size());
List<MovieItem> newMovieItems = response.body().getItems();
//sorted:
Arrays.sort(newMoviewItems, new Comparator() { some condition to sort });
HeaderItem liveHeader = new HeaderItem("Drama");
LiveChannelPresenter liveChannelPresenter = new LiveChannelPresenter();
ArrayObjectAdapter liveRowAdapter = new ArrayObjectAdapter(liveChannelPresenter);
for (int i = 0; i < newMovieItems.size(); i++) {
//note the change here \|/
movieItem2 = newMoviewItems.get(i);
liveRowAdapter.add(movieItem2);
}
mRowsAdapter.add(new ListRow(0,liveHeader,liveRowAdapter));
}
I am trying to integrate highcharts in my android app (inside fragment) but I am getting this error every time:

Here is my onCreateView Method:
#Override

}
How I am getting chart view:
chartView = parentView.findViewById(R.id.hc);
I am calling chart API to get to data after getting a response, I am setting options but it is giving me the same error, below is the code snippets how am I setting chart:

What am I missing here? Or How to resolve this issue?
I am able to solve the issue.
Follow below steps to resolve the issues:
When you fragment view is visible
Get highchart Id
chartView = parentView.findViewById(R.id.hc);
Set empty options to chartView:
HIOptions options = new HIOptions();
chartView.setOptions(options);
Once you get the data from your API set options to chartView again and call reload method:
chartView.setOptions(options);
chartView.reload();
Add the dependency again
implementation 'com.highsoft.highcharts:highcharts:7.0.3'
in the build.gradle file(app)
In my case It worked Well
I have tried to add a BarChart in my Code, nothing appear when I launch my app.
The purpose of my code is that: when the user enter the start date (StartDate), end date (EndDate) and the product name, the graph should show the show price evolution during that period.
I have tried the code below, but nothing appear on the graph.

A wild guess, without any more details provided: your're setting the x-axis min and max values to the start and end date. I'm guessing this is encoded in unix time, so you have something like 1470614400 and 1471219200.
Now looking at your data, it will start with 0 and go up to the number of prices you have in your price list (mPriceList.size()). So with 10 prices we'd have values at 0 through 9. However, since your x-axis starts at 1470614400, no data will be shown (although the axis, gridlines etc. should be visible).
So in order to fix your code (depending on how your price list is structured, this example assumes one price every hour), you'd need to change your code in setData to this:
for (int i = 0; i < mPriceList.size(); i++) {
yVals1.add(new BarEntry(mStartDate + i * 3600, mPriceList.get(i)));
}
If you have a list of dates associated with the price values, you can also simply do this:
for (int i = 0; i < mPriceList.size(); i++) {
yVals1.add(new BarEntry(mDateList.get(i), mPriceList.get(i)));
}
We the reply of(#TR4Android),
I have update my code such below and I can get the graph:
float start = 0f;
mChart.getXAxis().setAxisMinValue(start);
mChart.getXAxis().setAxisMaxValue(mPriceList.size());
for (int i = 0; i < mPriceList.size(); i++) {
yVals1.add(new BarEntry(i , mPriceList.get(i)));
}
But I have a bit issue with start date end date where each item has been bought. I have put each date in array list but I don't see how I can put it on xAxis. The Array list is :
private ArrayList<Long> mDateList = new ArrayList<Long>();
One example of mDateList value is 2016/08/13
I have 1 top layout and 3 bottom layouts, a user drags items from top layout to one of the 3 below.
The code below:
puts sequentially every image in every bottom layout into a list
removes items from each bottom layout
puts them back into top layout
public void onClick(View view) {
LinearLayout bottomLinearLayout1 = (LinearLayout) findViewById(R.id.bottom1);
LinearLayout bottomLinearLayout2 = (LinearLayout) findViewById(R.id.bottom2);
LinearLayout bottomLinearLayout3 = (LinearLayout) findViewById(R.id.bottom3);
LinearLayout topLinearLayout = (LinearLayout) findViewById(R.id.topLinear);
int total_num1 = bottomLinearLayout1.getChildCount();
int total_num2 = bottomLinearLayout2.getChildCount();
int total_num3 = bottomLinearLayout3.getChildCount();
View current_image = null;
List<View> listOfkids = new ArrayList<>() ;
//************ REPEATS **************
for(int i = 0 ; i < total_num1 ; i++){
current_image = bottomLinearLayout1.getChildAt(i);
listOfkids.add(current_image);
}
bottomLinearLayout1.removeAllViews();
for(int i = 0 ; i < listOfkids.size();i++){
topLinearLayout.addView( listOfkids.get(i));
}
listOfkids.clear();
//************ REPEATS **************
for(int i = 0 ; i < total_num2 ; i++){
current_image = bottomLinearLayout2.getChildAt(i);
listOfkids.add(current_image);
}
bottomLinearLayout2.removeAllViews();
for(int i = 0 ; i < listOfkids.size();i++){
topLinearLayout.addView( listOfkids.get(i));
}
listOfkids.clear();
//************ REPEATS **************
for(int i = 0 ; i < total_num3 ; i++){
current_image = bottomLinearLayout3.getChildAt(i);
listOfkids.add(current_image);
}
bottomLinearLayout3.removeAllViews();
for(int i = 0 ; i < listOfkids.size();i++){
topLinearLayout.addView( listOfkids.get(i));
}
Basically, the only difference between these loops is the last digit in "bottomLinearLayout"; the other code just copies itself!
Can i do this:
if(id == R.id.bottom1){
String current_layout = "bottomLinearLayout" + 1 ;
}
else if( id == R.id.bottom2){
current_layout = "bottomLinearLayout" + 2 ;
}
else if( id == R.id.bottom3){
current_layout = "bottomLinearLayout" + 3 ;
}
and then add this string as a command right into the java source code?
is this possible?
Assuming that you want to refactor the onClick method, you could create an array of the layout ids and iterate through them as follows:
int bottomLayoutIds[] = {R.id.bottom1, R.id.bottom2, R.id.bottom3};
LinearLayout topLinearLayout = (LinearLayout) findViewById(R.id.topLinear);
for (int layoutId : bottomLayoutIds){
LinearLayout bottomLinearLayout = (LinearLayout) findViewById(layoutId);
int childCount = bottomLinearLayout.getChildCount();
List<View> listOfKids = new ArrayList<>() ;
for(int i = 0 ; i < childCount ; i++){
View currentImage = bottomLinearLayout.getChildAt(i);
listOfKids.add(currentImage);
}
bottomLinearLayout.removeAllViews();
for(int i = 0 ; i < listOfKids.size();i++){
topLinearLayout.addView( listOfKids.get(i));
}
}
Below is Simple declaration in this a child and parent is being build with dynamic list value.With relevant code as createGroupList() and createChildList(). I am able to manipulate with TextView but one of field is my dynamic image from getting to JSON not is being load in WebView.
