Why my textview is show in single line when I start the app firstly?

I have a very wonderful problem in my app. I have a text view in my activity which get a text from sqlite like this:
Hello
World!
But when I start my app for first time, My text view show the text like this:
Hello word!
When I go out from app and clear my app form RAM and then comeback to the app my text view show the text currectly like this:
Hello
World!
In fact, when onCreate method run for first time my text view text show in single line. I tried very ways like use recreate method:
public void recreate() {
this.recreate();
}
And in onCreate method:
recreate();
But my app crashed!
Is there a way to solve this problem? Thanks

removeAllView() and removeAllViewsInLayout() is not removing

Thanks in advance and here is my problem. I have a database and i have to show its content whenever the "SHOW DATA" button is clicked (on the same activity (layout)). so when the user clicks again that button i want to remove the views in the layout so that the content of the database is not shown twice. I've have used removeAllView() and removeAllViewsInLayout() but it seems it's not working (for sure i'm not using correctly this method).
Here is the java code :
public void onClickShowData(){
LinearLayout ll = (LinearLayout) findViewById(R.id.cardViewContainer);
ll.removeAllViews();
showAll.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Cursor cursor = myDB.getAllData();
if (cursor.getCount() == 0) {
//Toast.makeText(MainActivity.this, "There is no data", Toast.LENGTH_SHORT).show();
showData("Error", "Nothing found");
return;
}
StringBuffer tmp = new StringBuffer();
LinearLayout ll = (LinearLayout)findViewById(R.id.cardViewContainer);
Context context = getApplicationContext();
LinearLayout ll2 = new LinearLayout(context);
ll2.setOrientation(LinearLayout.VERTICAL);
ll2.setLayoutParams(new ActionBar.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
TextView tv = new TextView(context);
CardView cv = new CardView(context);
cv.setId(R.id.cardView);
while (cursor.moveToNext()){
tmp.append("name : " + cursor.getString(0) + "\n" +
"calory : " + cursor.getString(1) + "\n" +
"protein : " + cursor.getString(2) + "\n" +
"lipid : " + cursor.getString(3) + "\n" +
"clucid: " + cursor.getString(4));
ll.addView(cv);
cv.addView(ll2);
tv.setText(tmp.toString());
ll2.addView(tv);
}
}
}
);
}

enter code here
When the app starts
When i click 3 times on show DB

You have to remove
LinearLayout ll = (LinearLayout) findViewById(R.id.cardViewContainer);
This line from inside onClickShowData() method and, add
LinearLayout ll;
To the top of your activity class.
then in onCreate(Bundle savedInstanceState) method add,
ll = (LinearLayout) findViewById(R.id.cardViewContainer);
In your current code, you are adding views to an ll and calling ll.removeAllViews() in a different object.
the final code should be something like,
public class YourActivityName extends Activity {
LinearLayout ll;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ll = (LinearLayout) findViewById(R.id.cardViewContainer);
// .... other code //
}
public void onClickShowData(){
ll.removeAllViews();
showAll.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Cursor cursor = myDB.getAllData();
if (cursor.getCount() == 0) {
//Toast.makeText(MainActivity.this, "There is no data", Toast.LENGTH_SHORT).show();
showData("Error", "Nothing found");
return;
}
StringBuffer tmp = new StringBuffer();
Context context = getApplicationContext();
LinearLayout ll2 = new LinearLayout(context);
ll2.setOrientation(LinearLayout.VERTICAL);
ll2.setLayoutParams(new ActionBar.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
TextView tv = new TextView(context);
CardView cv = new CardView(context);
cv.setId(R.id.cardView);
while (cursor.moveToNext()){
tmp.append("name : " + cursor.getString(0) + "\n" +
"calory : " + cursor.getString(1) + "\n" +
"protein : " + cursor.getString(2) + "\n" +
"lipid : " + cursor.getString(3) + "\n" +
"clucid: " + cursor.getString(4));
ll.addView(cv);
cv.addView(ll2);
tv.setText(tmp.toString());
ll2.addView(tv);
}
}
}
);
}
}

You are setting your onClick() listener with showAll.setOnClickListener but the code that gets executed does not include ll.removeAllViews(). Change your click listener to something like the following to remove views when the button is clicked.
showAll.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
LinearLayout ll = (LinearLayout) findViewById(R.id.cardViewContainer);
ll.removeAllViews();
...etc.

More than 3 items per sub items GridView Android

I want to display the data from content provider in gridview more than 3 sub items or line
here is my java source code
#Override
public void onLoadFinished(Loader<Cursor> arg0, Cursor cursor) {
players.clear();
// First Check if cursor is not null
if(cursor != null ) {
StringBuilder result = new StringBuilder();
// Now loop to all items and append it to string builder
while (cursor.moveToNext()) {
String id = cursor.getString(cursor.getColumnIndex("ID"));
String name = cursor.getString(cursor.getColumnIndex("ITEM_NAME"));
String qty = cursor.getString(cursor.getColumnIndex("QUANTITY"));
String inst = cursor.getString(cursor.getColumnIndex("INSTRUCTION"));
String pid = cursor.getString(cursor.getColumnIndex("POS_ID"));
players.add("Items :" + name + "\n" + "Qty :" + qty + "\n" +
"Details :" + inst + "\n" + " Pos ID :" + pid);
gv.setAdapter(adapter);
resultView.setText(result);
}
} else {
// If cursor is null then display toast amd set empty data.
resultView.setText("Empty data");
Toast.makeText(MainActivity.this, "May be there is no app corresponding to your provider or there is null data.",

Any idea or help will do
Thanks a lot guys

You need make height of GridView is match_parent/wrap_content (based on your layout), don't fix size 420dp

android Set text is not working for me

I am trying get the weather details like temp and condition and I am unable to Display them But I am able to see them in my log cat code.
Here is my code follows
cond = (TextView) findViewById(R.id.condDescr);
temp = (TextView) findViewById(R.id.tempText);
temp.setText("HI How are you");
JSONWeatherTask task = new JSONWeatherTask();
task.execute(new String[]{city});

Weather weather = new Weather();
String data = ( (new WeatherHttpClient()).getWeatherData(params[0]));
try {
weather = JSONWeatherParser.getWeather(data);
// Let's retrieve the icon
//weather.iconData = ( (new WeatherHttpClient()).getImage(weather.currentCondition.getIcon()));
} catch (JSONException e) {
e.printStackTrace();

String str2 = ("" + weather.currentCondition.getHumidity() + "%");
Log.w("myApp", str1);
Log.w("mytemp", str2);

And I have also tried like manual data set but it is not working for me. I dont know what was my mistake could any one tell me how to solve this.

In order to call the method doInBackground of your ASyncTask, you need to add task.execute(params).
params can be either a String or multiple Strings separated by ,
In your case, you should pass to execute the data needed by the method getWeatherData().

Android: Dynamically Populate a SlidingDrawer (or a small list) within the Main Activity

I am working on an Android mapping app that allows a user to type a search parameter into an EditText box, and then the closest destinations matching the query are plotted with pins on the MapView.
Clicking on a pin will give info about the location, but I would like to provide more information to the user up front. I thought a SlidingDrawer could populate and open up to show the user the names of the destinations/the distances away.
Having spent a lot of time on this, having done much reading, and having made little progress, I am now asking the community for assistance.
The problem I'm having is that I can't figure out how to populate the contents of the SlidingDrawer within the main activity. I am able to launch a new activity, but that takes my MapView off the screen. I need to be able to see the map as well as the SlidingDrawer. And I can't figure out how to populate the SlidingDrawer without it being set up as an Activity.
(And I should say also that it doesn't necessarily need to be a SlidingDrawer that contains the list of destinations. I could modify my layout to make a small (max 3 items) list and take away some of the map's real estate if that is easier, but I'm not sure how to do that, either.)
Here is the code that calls my SlidingDrawer:
//call SlidingDrawer
Intent drawerIntent = new Intent(this, SlidingDrawerFinal.class);
drawerIntent.putExtra("lat", lat);
drawerIntent.putExtra("lon", lon);
int numberOfTargetsForList = numberOfLoops;
drawerIntent.putExtra("numberOfTargetsForList", numberOfTargetsForList);
for(int i = 0; i < target.length; i++){
drawerIntent.putExtra("target" + Integer.toString(i), target[i]);
}
this.startActivity(drawerIntent);
This is the code in my SlidingDrawer class (extends Activity) that fills the list inside the drawer:
View inflatedDrawerLayout = getLayoutInflater().inflate(R.layout.drawer_main, null);
int width = getWindow().getAttributes().width;
int height = 300;
LayoutParams params = new LayoutParams(width, height);
getWindow().addContentView(inflatedDrawerLayout, params);
// add some data
ArrayList<MyData> myDataList = new ArrayList<MyData>();
myData = new MyData[numberOfTargets];
for(int i = 0; i < numberOfTargets; i++){
String lineTwo = "";
if(target[i].getRating().equals("Not Yet Rated")){
lineTwo = " " + target[i].getRating() + " " +
Double.toString((Math.round(target[i].getDistance()*100.0))/100.0) + " miles";
}
else{
lineTwo = " rating: " + target[i].getRating() + "/5 stars " +
Double.toString((Math.round(target[i].getDistance()*100.0))/100.0) + " miles";
}
String lineOne = (Integer.toString(i + 1) + ": " + target[i].getName() + ", " + target[i].getVicinity()) + "\n" + lineTwo;
myData[i] = new MyData(lineOne, i);
myDataList.add(myData[i]);
}
mListView = (ListView) findViewById(R.id.listview_);
mListView.setAdapter(new MyListAdapter(this, R.layout.drawer_row, myDataList));
drawer = (SlidingDrawer) findViewById(R.id.drawer);
handleButton = (Button) findViewById(R.id.handle);
drawer.animateOpen();
drawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {
public void onDrawerOpened() {
handleButton.setBackgroundResource(R.drawable.handle_down_white);
}
});

Sorry that this is so lengthy. Any assistance will be greatly appreciated.

You can use Popup Window.
View popupView = layoutInflater.inflate(R.layout.popup_window, null);
final PopupWindow popupWindow = new PopupWindow(popupView,
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
ImageButton btnCancel = (ImageButton) popupView
.findViewById(R.id.btnCancel);
popupWindow.showAtLocation(LayoutView, Gravity.BOTTOM
| Gravity.CENTER_HORIZONTAL, (LayoutView.getWidth() - popupView
.getWidth()) / 2, LayoutView.getHeight()
- popupWindow.getHeight() - 10);
popupWindow.setAnimationStyle(Animation.RELATIVE_TO_SELF);
popupWindow.setFocusable(true);
popupWindow.update();

The solution I opted for is programmatically a bit less than ideal, but the layout works well. Since I knew I wouldn't have more than 3 results, I just changed my layout to include (up to) 3 small TextViews under my search bar and (sadly) got rid of the SlidingDrawer altogether. When the results come back, I populate as many TextViews as necessary, each with an onClickListener. It won't scale well, and everything is hard-coded; but it works. I may try to improve upon this solution as I learn more about Android.

new code:

//first line in list
barOverOne.setVisibility(View.VISIBLE);

lineOne.setText(detailsForLineOne);
lineOne.setOnClickListener(this);
i++;
...(similar blocks handle cases of i = 1 and i =2)
Finally, in my onClick() method:
case R.id.line_one:{
String locForURL = "origin=" + Double.toString(lat/1000000.0) +
"," + Double.toString(lon/1000000.0) + "&destination=" +

Intent intent = new Intent(this, ParsingXMLDirectionsWithListView.class);
intent.putExtra("dirTitle", target[0].getName()+ " (" +
Double.toString((Math.round(target[0].getDistance()*100.0))/100.0) + " miles)");
intent.putExtra("locForURL", locForURL);
this.startActivity(intent);
break;
}//line_one
...(similar blocks for lines two and three)
Not perfect, but oh well. At least looks pretty good from the user's end, and I was never going to meet my deadline by continuing down the SlidingDrawer route. Maybe when I have some more free time I'll see if I can figure that out....
