so how to repaint my chart? i hope somebody can show me where is my fault, and tell me the way to fix it
Use chartView.removeView(Graphical_View)
before setting the chart view with new values, followed by use the 'Graphical_View.repaint()' inorder to set new value to the layout
However use multirenderer.setInScroll(true);
Hard to understand the question, but I will try to guess.
In order to repaint the chart, you need to call chartView.repaint();
However, the issue you have may be fixed by having an mRenderer.setInScroll(true); call.
I slove this problem using this code
if(layout != null)
layout.removeAllViews();
layout.addView(mChartView, new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
mChartView = null;

here I CREATE place to fill by selected letter by user:
private void createWord(int length) {
LinearLayout world_layout = (LinearLayout) findViewById(R.id.world_layout);
LayoutParams param = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, length);
word_btn = new Button[length];
for (int i = 0; i < length; i++) {
word_btn[i] = new Button(getApplicationContext());
word_btn[i].setText("");
word_btn[i].setId(i);
word_btn[i].setTextColor(Color.parseColor("#ffffff"));
word_btn[i].setTextSize(24);
word_btn[i].setTypeface(Typeface.DEFAULT_BOLD);
word_btn[i].setLayoutParams(param);
word_btn[i].setBackgroundResource(R.drawable.matchbox);
world_layout.addView(word_btn[i]);
word_btn[i].setOnClickListener(charOnClick(word_btn[i]));
}
}
and here i check the letters to fill:
private void createResult() {
resultWord = "";
for (int i = 0; i < word_array.length; i++) {
if (word_btn[i].getText() != "") {
resultWord +=word_btn[i].getText();
}
}
if (resultWord.length() == word_array.length) {
if (resultWord.equalsIgnoreCase(theWord)) {
showMyDialog(1, null);
} else {
showMyDialog(2, null);
}
}
}
now it works but my button fill from left to right
I want to fill right to left
Try adding android:supportsRtl="true" in <application> in your AndroidManifest.xml, and then android:layoutDirection="rtl" in your root layout.
Using a check if the language is right to left from this answer, I would structure your code like this:
private static boolean isRTL() {
final int directionality = Character.getDirectionality(Locale.getDefault().getDisplayName().charAt(0));
return directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT ||
directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT_ARABIC;
}
private void populateButtons(int i, Button word_btn) {
word_btn[i] = new Button(getApplicationContext());
word_btn[i].setText("");
word_btn[i].setId(i);
word_btn[i].setTextColor(Color.parseColor("#ffffff"));
word_btn[i].setTextSize(24);
word_btn[i].setTypeface(Typeface.DEFAULT_BOLD);
word_btn[i].setLayoutParams(param);
word_btn[i].setBackgroundResource(R.drawable.matchbox);
world_layout.addView(word_btn[i]);
word_btn[i].setOnClickListener(charOnClick(word_btn[i]));
}
private void createWord(int length) {
LinearLayout world_layout = (LinearLayout) findViewById(R.id.world_layout);
LayoutParams param = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, length);
word_btn = new Button[length];
if(isRTL()) {
for(int j = length - 1; j >= 0; j--) {
populateButtons(j, word_btn);
}
} else {}
for (int k = 0; k < length; k++) {
populateButtons(k, word_btn)
}
}
After 2 days, I found the solution. It was easy as a piece of cake.
I dont know why I make it so compilacated.
I just change the my if clause like this:
for (int i = length -1; i >= 0; i--) {
word_btn[i] = new Button(getApplicationContext());
word_btn[i].setText("");
word_btn[i].setId(i);
word_btn[i].setTextColor(Color.parseColor("#ffffff"));
word_btn[i].setTextSize(24);
word_btn[i].setTypeface(Typeface.DEFAULT_BOLD);
word_btn[i].setLayoutParams(param);
word_btn[i].setBackgroundResource(R.drawable.matchbox);
world_layout.addView(word_btn[i]);
word_btn[i].setOnClickListener(charOnClick(word_btn[i]));
}
I have one quote application. I have implemented share and copy function in it. I am facing issue is that I am not getting shared first time sharing quote. Means if there 50 quote in list and if I try to share any quote from list than it is not sharing anything. after that if I move on another quote and try to sharing than its working fine. I have same issue in copy function also. I also face some time issue like if I share quote number 50 than its sharing another number quote. Please help me for solve the bug. Thanks

To Show only 10 item first time in ListView and show more items on scroll follow following steps:
STEP 1: Create a chunkList method which divide ArrayList in parts of size 10:
static <T> List<ArrayList<T>> chunkList(List<T> list, final int L) {
List<ArrayList<T>> parts = new ArrayList<ArrayList<T>>();
final int N = list.size();
for (int i = 0; i < N; i += L) {
parts.add(new ArrayList<T>(
list.subList(i, Math.min(N, i + L)))
);
}
return parts;
}
STEP 2: Create ArrayList and a counter which show current part :
private boolean isLoadingMore=false;
Handler mHandler = new Handler();
List<ArrayList<HashMap<String,String>>> mainArrayList;
private int count=0;
STEP 3: In onPostExecute break result and show data in ListView:
protected void onPostExecute(ArrayList<HashMap<String,String>> result) {
super.onPostExecute(result);
// your code here...
mainArrayList=chunkList(result,10);
isLoadingMore=false;
count=0;
adapter = new CustomAdapterSent(Interestsent.this,
mainArrayList.get(count));
setListAdapter(adapter);
}
}
STEP 4: Create addAll method in Adapter to append data in current data source :
public void addAll(ArrayList<HashMap<String,String>> moreData){
this.listData.addAll(moreData);
this.notifyDataSetChanged();
}
STEP 5: In onLoadMore load more data in ListView:
mHandler = new Handler();
listview.setOnScrollListener(new EndlessScrollListener() {
#Override
public void onLoadMore(int page, int totalItemsCount) {
if(count<mainArrayList.size()-1)
{
if(adapter !=null){
count++;
if(!isLoadingMore){
isLoadingMore=true;
mHandler.postDelayed(loadMoreRunnable,1000);
}
}
}
}
});
}
Runnable loadMoreRunnable = new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
if(count<mainArrayList.size())
{
if(adapter !=null){
count++;
adapter.addAll(mainArrayList.get(count));
mHandler.removeCallbacks(loadMoreRunnable);
isLoadingMore=false;
}
}
}
};
To have an AdapterView (such as a ListView or GridView) that automatically loads more items as the user scrolls through the items (aka infinite scroll). This is done by triggering a request for more data once the user crosses a threshold of remaining items before they've hit the end. Every AdapterView has support for binding to the OnScrollListener events which are triggered whenever a user scrolls through the collection. Using this system, we can define a basic EndlessScrollListener which supports most use cases by creating our own class that extends OnScrollListener.
You can find more about this in the below links :

Infinite Scrolling List View
A simpler approach of adding data in a listview has been show in this SO answer: Android Endless List
Hope this helps ...
I am developing an app like Logo Quiz ... This is the activity, where you have to write the name of the logo:
public class Vie extends Activity implements OnClickListener {
ImageView img;
EditText et;
Button btn;
TextView txt;
MediaPlayer win_sound, wrong_sound;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.vie);
img = (ImageView) findViewById(R.id.img);
et = (EditText) findViewById(R.id.et);
btn = (Button) findViewById(R.id.btnCheck);
txt = (TextView) findViewById(R.id.txt);
win_sound = MediaPlayer.create(Vie.this, R.raw.win);
wrong_sound= MediaPlayer.create(Vie.this, R.raw.wrong);
setImageAndTagByIntent(img);
btn.setOnClickListener(this);
}
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
boolean mb = check(et, img);
Intent i = getIntent();
if (mb) {
// Sunet toast thread
txt.setText(title(img));
win_sound.start();
i.putExtra("score", "1");
setResult(RESULT_OK, i);
Thread t = new Thread() {
#Override

// TODO Auto-generated method stub
super.run();
try {

} catch (Exception e) {
// TODO: handle exception

}
if (!mb) {
// sunet toast thread
wrong_sound.start();
Toast t = Toast.makeText(getApplicationContext(),"Wrong answer! Please check if you have spelled corectly the name of the team!",Toast.LENGTH_LONG);

}
}

// TODO Auto-generated method stub

return s;
}

// TODO Auto-generated method stub
// Trece si tagul!
Intent i = getIntent();
Bitmap back = i.getParcelableExtra("back");
Drawable b = new BitmapDrawable(getResources(), back);
img2.setImageDrawable(b);
String tag = i.getStringExtra("tag");
Object tag2 = (Object) tag;
img2.setTag(tag2);
}
private boolean check(EditText et2, ImageView img2) {
// TODO Auto-generated method stub
String s = et2.getText().toString();
s = WordUtils.capitalize(s);
String s1 = (String) img2.getTag();
boolean b;
if ((s1.contains("") && s.contentEquals(firstWord(s1)))||(s.contentEquals(s1) && !s1.contains(""))) {

}else {
b=false;
}
return b;
}
private String firstWord(String s1) {
// TODO Auto-generated method stub
String arr[] = s1.split("//s");
return arr[0];
}
}
It works ... but when the name of the logo has two words and when I put only the first word, it says that it is wrong! It works only with the full name. Please Help Me!
Change the below condition:
private String firstWord(String s1) {
// TODO Auto-generated method stub
String arr[] = s1.split(" ");
return arr[0];
}
Also change your if condition:
((s1.contains(" ") && s.contentEquals(firstWord(s1)))||(s.contentEquals(s1) && !s1.contains(" ")))
I think it's a problem with your firstWord function. Try changing it to:
private String firstWord(String s1) {
String arr[] = s1.split(" ");
return arr[0];
}
Also, change this:
if ((s1.contains("") && s.contentEquals(firstWord(s1)))||(s.contentEquals(s1) && !s1.contains("")))
To:
if ((s1.contains(" ") && s.contentEquals(firstWord(s1)))||(s.contentEquals(s1) && !s1.contains(" ")))
I am having a problem on the line where I call the query to PostCategoryContent Provider

On which line is the exception thrown? The problem is more likely an issue with your SQLite syntax than with anything having to do with Loaders or Cursors. Make sure your table is getting initialized as you require. Do a DatabaseUtils.dumpCursor(cursor) to analyze the contents of the Cursor between the exception is thrown. Also, I would look into your use of LIKE... I have seen people having issues with that keyword before.
