Opening PlacePicker on SearchView single click

Opening PlacePicker on SearchView single click - android

I'm using SearchView as below in my code :
xml :
<android.support.v7.widget.SearchView
android:id="#+id/searchView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="false"
android:focusable="false"
app:iconifiedByDefault="false"
app:queryBackground="#color/transparant"
app:queryHint="#string/search"
app:searchIcon="#drawable/ic_search">
Java :
mSearchView = (SearchView) rootView.findViewById(R.id.searchView);
txtSearchText = (TextView) mSearchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
txtSearchText.setOnClickListener(this);
onCLick :
case R.id.search_src_text:
loadPlacePicker();
break;
But, the issue is SearchView needs a double click to open up PlacePicker.
I need to open PlacePicker on the single onClick Event of SearchView. How do I do that?

You need to change the value of searchView attribute clickable & focusable to true
<android.support.v7.widget.SearchView
android:id="#+id/searchView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
app:iconifiedByDefault="false"
app:queryBackground="#color/transparant"
app:queryHint="#string/search"
app:searchIcon="#drawable/ic_search">

urlArrayList gets updated correctly when database changes occur, but favoriteJsonArray, which is updated inside AsyncTask, does not. Why?

There are two problems in you code:
in FetchFavorites.doInBackground(), you assign a new JSONArray() to favoriteJsonArray, but your mAdapter is still hold the old reference, which is an empty JSONArray.
you didn't call mAdapter.notifyDataSetChanged() after update the favoriteJsonArray.
You can solve the problems in to ways:
do not new JSONArray() in FetchFavorites.doInBackground(), and call mAdapter.notifyDataSetChanged() after update the favoriteJsonArray, but there is still a problem, you should clear the favoriteJsonArray every time you fetch the new data, and clear a JSONArray is kind of boring (there is no clear() method).
new JSONArray(), but edit your MainActivityAdapter, add a method like setFavorites(JSONArray array), and set the new created favoriteJsonArray to it then call mAdapter.notifyDataSetChanged().

Android get attribute value from xml

I am trying to make an app which uses last.fm's web API, sends a query for similar artists and returns all the names of the similar artists. It seems as though I manage to connect and get the xml response properly. However, I cannot extract the value of the name-attribute. I am using artistName = xmlData.getAttributeValue(null, "name"); but all it gives me is null.

Log.i("my tag.... ", "name = " + foundArtistName);

}
}
}
Here's a screenshot of the xml response in Google Chrome:
The only thing I am interested in extracting at this moment is the the value of the Name-Element.
I am logging the value of foundArtistName (in the method notifyObserver) it gives me A LOT of "my tag.... name = null my tag.... name = null my tag.... name = null etc.."
EDIT: I tried using getText() instead of getAttributeValue(), but it also gives me null.

I found the solution. I was using: artistName = xmlData.getAttributeValue(null, "name");, when I really should've used: artistName = xmlData.nextText();

My list is loading again when I am Pressing Back Button

I am also getting ArrayListIndexOutofBound when I am pressing list item when the orientation is changed.As far my knowledge of android I have written Parcelable code correctly.But I think my issues are with the recycler view setup.I am confused with two declaration of my adapter.Help me

Now I get it after years.I would have simply used.
FLAG_ACTIVITY_CLEAR_TOP - If set, and the activity being launched is already running in the current task, then instead of launching a new instance of that activity, all of the other activities on top of it will be closed and this Intent will be delivered to the (now on top) old activity as a new Intent.

RingtonePreference Theme

Im creating an Android App, totaly in Holo.Light Theme.
All the preferences are light, except for the Ringtonepreference!
I have even tried setting the BGColor and the textColor in the Preferences.xml:
<RingtonePreference
android:icon="#drawable/ic_menu_note"
android:key="ringtone"
android:persistent="true"
android:summary="#string/settings_ringtone2"
android:background="#000000"
android:textColor="#ffffff"
android:title="#string/settings_ringtone" />
Android ignores everything..
Has anybody a clue on how to change the Theme of the RingtonePreference to Holo.Light?

I have found an answer myself, couse as it seems, no App can touch the Ringtonemanager's settings..
So what I did is extending the Listpreference:
package de.Psychologie.socialintelligence;
import java.io.IOException;
import android.app.AlertDialog.Builder;
import android.content.Context;
import android.content.DialogInterface;
import android.content.res.TypedArray;

private int mClickedDialogEntryIndex;
private String mValue;
public CustomRingtonepreference(Context context, AttributeSet attrs) {
super(context, attrs);
}

}

mValue = value;
persistString(value);
}
/**
* Sets the value to the given index from the entry values.
*
* #param index The index of the value to set.
*/
public void setValueIndex(int index) {
if (mEntryValues != null) {
setValue(mEntryValues[index].toString());
}
}
/**
* Returns the value of the key. This should be one of the entries in
* {#link #getEntryValues()}.
*

*/
public String getValue() {
return mValue;
}
/**

*/
public CharSequence getEntry() {
int index = getValueIndex();
return index >= 0 && mEntries != null ? mEntries[index] : null;
}
public int findIndexOfValue(String value) {
if (value != null && mEntryValues != null) {
for (int i = mEntryValues.length - 1; i >= 0; i--) {
if (mEntryValues[i].equals(value)) {
return i;
}
}
}
return -1;
}
private int getValueIndex() {
return findIndexOfValue(mValue);
}
#Override
protected void onPrepareDialogBuilder(Builder builder) {
super.onPrepareDialogBuilder(builder);
mMediaPlayer = new MediaPlayer();
mEntries = getEntries();
mEntryValues = getEntryValues();
if (mEntries == null || mEntryValues == null) {
throw new IllegalStateException(

builder.setSingleChoiceItems(mEntries, mClickedDialogEntryIndex,

try {

} catch (IllegalStateException e) {

} catch (IOException e) {

}
}
});
builder.setPositiveButton("OK", this);
builder.setNegativeButton("Abbrechen", this);
}
private void playSong(String path) throws IllegalArgumentException,
IllegalStateException, IOException {
//Log.d("ringtone", "playSong :: " + path);
mMediaPlayer.reset();
mMediaPlayer.setDataSource(path);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_RING);
// mMediaPlayer.setLooping(true);
mMediaPlayer.prepare();
mMediaPlayer.start();
}
#Override

}

}
public SavedState[] newArray(int size) {
return new SavedState[size];
}
};
}
#Override

super.onDialogClosed(positiveResult);
if (positiveResult && mClickedDialogEntryIndex >= 0 && mEntryValues != null) {
String value = mEntryValues[mClickedDialogEntryIndex].toString();
if (callChangeListener(value)) {
setValue(value);
}
}
mMediaPlayer.stop();
mMediaPlayer.release();
}
#Override
protected Object onGetDefaultValue(TypedArray a, int index) {
return a.getString(index);
}
#Override
protected void onSetInitialValue(boolean restoreValue, Object defaultValue) {
setValue(restoreValue ? getPersistedString(mValue) : (String) defaultValue);
}
#Override
protected Parcelable onSaveInstanceState() {
final Parcelable superState = super.onSaveInstanceState();
if (isPersistent()) {
// No need to save instance state since it's persistent
return superState;
}
final SavedState myState = new SavedState(superState);
myState.value = getValue();
return myState;
}
}
And vor adding the Values I chose the Programmatical way:
//Import All Ringtones
RingtoneManager rm = new RingtoneManager(UserSettingActivity.this);
rm.setType(RingtoneManager.TYPE_ALARM|RingtoneManager.TYPE_RINGTONE );
final Cursor ringtones = rm.getCursor();
List<String> mEntries = new ArrayList<String>();
List<String> mEntryValues = new ArrayList<String>();
for (ringtones.moveToFirst(); !ringtones.isAfterLast(); ringtones.moveToNext()) {
mEntries.add(ringtones.getString(RingtoneManager.TITLE_COLUMN_INDEX));
mEntryValues.add(ringtones.getString(RingtoneManager.URI_COLUMN_INDEX));
}
ringtonepref.setEntryValues(mEntryValues.toArray(new CharSequence[mEntryValues.size()]));
ringtonepref.setEntries(mEntries.toArray(new CharSequence[mEntries.size()]));
And for the initial Initiation with the default Ringtone:
//Sets the default Alarm to the chosen Value
ringtonepref.setValue(RingtoneManager.getActualDefaultRingtoneUri(getBaseContext(), RingtoneManager.TYPE_ALARM).toString());
I hope it helps someone ;)

Well, after spending half the night to get it working, I got a proper solution. I took the advice Trinitrotoluol has written here and merged this with my own functionality. Here is my CustomListPreference (complete, with no step missing)...
import android.app.AlertDialog.Builder;

entryValues.add(ringtones.getString(RingtoneManager.URI_COLUMN_INDEX) + "/" + id);
Log.d(TAG, "Tone: " + ringtones.getString(RingtoneManager.URI_COLUMN_INDEX) + "/" + id);
}
setEntryValues(entryValues.toArray(new CharSequence[entryValues.size()]));
setEntries(entries.toArray(new CharSequence[entries.size()]));
}
public CustomListPreference(Context context) {
super(context);

}
}
}
return -1;
}
private int getValueIndex() {

#Override

}
builder.setSingleChoiceItems(mEntries, mActivePositionInList,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
mActivePositionInList = which;
String path = mEntryValues[which].toString();
try {
RingtoneManager.getRingtone(getContext(), Uri.parse(path)).play();
mPath = path;
} catch (Exception e) {

builder.setPositiveButton("OK", this);

}
if (!positiveResult) {
Log.d(TAG, "neg");
mPath = mTmpPath;
mActivePositionInList = mTmpActivePositionInList;
setOldValues();
}
}
}
to get it right in front on the screen, you can add this snippet to your prefs.xml
<de.yourpackage.right.activities.CustomListPreference
android:dialogTitle="Some text"
android:summary="some text too"
android:title="and more text"
/>
Finally I'm quite happy to get it working now..
PS: if you have questions, feel free to ask.
