[Q] ExpandableView inside another ExpandableView won't inflate children

I've been struggling for a couple of weeks to solve this problem. I have two expandable views, one inside another. Whenever i click on the second level expandable view items, it won't inflate its children. All i see when i click is a small scroll bar that appears on the right side on the expandable view item itself. Using a simple layout with a fixed textview results in the same behaviour, meaning that the problem isn't within the ShiftListItem object/s.
Also, getChildView() is never been called.

}

Adding custom apps to an app switcher panel

I am currently working on an App Switcher with the ability to also add custom apps in the app switcher. So, I already got the recent apps loader built. This is the code for this part of the app:
Code:
public class Corners_RecentApps extends Activity {
private ArrayList<PanelItemDetail> rowItems = null;
private ListView listView;
private ArrayList<String> packageName = null;
private ArrayList<String> className = null;
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
boolean rightpanel = getSharedPreferences(getPackageName() + "_preferences", Context.MODE_PRIVATE).getBoolean("panelpos_right", true);
if(rightpanel){
overridePendingTransition(R.anim.left_slide_in_fast, 0);
setContentView(R.layout.right_side_panel);
}
else
{
overridePendingTransition(R.anim.right_slide_in_fast, 0);
setContentView(R.layout.activity_left_side_panel);
}
ImageView imgbtn = (ImageView) findViewById(R.id.transparentbackground);
ImageView panelbg = (ImageView) findViewById(R.id.panelbackground);
listView = (ListView)findViewById(R.id.panelcontents);
packageName = new ArrayList<String>();
className = new ArrayList<String>();
ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
List<ActivityManager.RecentTaskInfo> tasks = am.getRecentTasks(30, 0);
rowItems = new ArrayList<PanelItemDetail>();
PackageManager pacMgr = getPackageManager();
for (ActivityManager.RecentTaskInfo recentTask : tasks) {
try {
rowItems.add(new PanelItemDetail(pacMgr.getApplicationIcon(recentTask.origActivity.getPackageName())));
packageName.add(recentTask.origActivity.getPackageName());
className.add(recentTask.origActivity.getClassName());
Log.d("#@#", "getPackageName = " + recentTask.origActivity.getPackageName());
Log.d("#@#", "getClassName = " + recentTask.origActivity.getClassName());
} catch (NameNotFoundException e) {
e.printStackTrace();
}
}
SharedPreferences myPreference = PreferenceManager.getDefaultSharedPreferences(this);
String itembg = myPreference.getString("itembg_list", "");
if(itembg.equals("defaults"))
{
PanelArrayAdapter adapter = new PanelArrayAdapter(this,R.layout.panelrow_default, rowItems);
listView.setAdapter(adapter);
}
else if(itembg.equals("dark"))
{
PanelArrayAdapter adapter = new PanelArrayAdapter(this,R.layout.panelrow_dark, rowItems);
listView.setAdapter(adapter);
}
else if(itembg.equals("light"))
{
PanelArrayAdapter adapter = new PanelArrayAdapter(this,R.layout.panelrow_light, rowItems);
listView.setAdapter(adapter);
}
else
{
PanelArrayAdapter adapter = new PanelArrayAdapter(this,R.layout.panelrow_none, rowItems);
listView.setAdapter(adapter);
}
listView.setOnItemClickListener(new OnItemClickListener() {
[user=439709]@override[/user]
public void onItemClick(AdapterView<?> parent, View view, int postion, long id) {
try{
boolean rightpanel = getSharedPreferences(getPackageName() + "_preferences", Context.MODE_PRIVATE).getBoolean("panelpos_right", true);
Intent taskintent = getPackageManager().getLaunchIntentForPackage(packageName.get(postion).toString());
startActivity(taskintent);
if(rightpanel){
overridePendingTransition(R.anim.right_slide_in, R.anim.zoom_out);
}
else
{
overridePendingTransition(R.anim.left_slide_in, R.anim.zoom_out);
}
finish();
}
catch (NullPointerException fail) {
Toast.makeText(getApplicationContext(), "!", Toast.LENGTH_SHORT).show();
}
}
});
SharedPreferences panelbgpref = PreferenceManager.getDefaultSharedPreferences(this);
String panelbgset = panelbgpref.getString("panelbg_list", "");
if(panelbgset.equals("light"))
{
panelbg.setImageResource(R.drawable.panelbg_light);
}
else
{
panelbg.setImageResource(R.drawable.panelbg);
}
imgbtn.setOnClickListener(new View.OnClickListener(){
[user=439709]@override[/user]
public void onClick(View v) {
if(v.getId() ==R.id.transparentbackground){
moveTaskToBack(true);
finish();
}
}
});
}
Now I want to let the users define in the app settings up to 3 own apps that should be shown on every moment.
How should I do that?
Thank you

Data Traffic Meter

Hi!
I'm developing an App that register the data speed sended and received. The problem is that the app shows a very similar speed between upload and upload, and the data speed seems to be incorrect.
Could anyone solve my problem?
Sorry form my BAD English [emoji29]
This is my code:
Code:
public class Traffic extends TextView {

mTxRate = (getTotalDataBytes(false) - mLastTransmit);
mRxRate = (getTotalDataBytes(true) - mLastReceive);
mLastReceive = getTotalDataBytes(true);
mLastTransmit = getTotalDataBytes(false);
Traffic.this.setText(formatSize(mTxRate/3) + "\n" + formatSize(mRxRate/3));
} else {

}
mHandler.postDelayed(task, mDelaytime);
}
};

}
}
Thanks!!

Come on please! :'(

Click to expand...
Click to collapse
Maybe this help: https://github.com/NetEase/Emmagee

I don't understand Chinese xD
And it doesn't help me... but anyway Thanks!
Any other solution?

Oh didnt see that, but there are other data traffic apps on github just search with google. Sorry thats all i can do

[Q] Button MaskFilter?

Hi,
I'm trying to apply a Mask or Blur Filter to some buttons at runtime... This button is reflecting a "layer" object, so I'd like to blur its edges to reflect how transparent is this layer...
I'm able to set a ColorFilter, or apply a maskFIlter to its TextView, but cant figure how to apply a maskFilter to the whole button...
here is the part of my code where I'd like to apply this filter (in a applyFilter method):
Code:
public void createList(LinearLayout lm) {
lm.removeAllViews();
for (int i = 0; i < kwang07Android.nblayers; i++) {
final Button newbtn = new Button(this, null, android.R.attr.buttonStyleSmall);
int col = kwang07Android.layers[i].col;
int newColor = Color.argb(156+(int)(kwang07Android.layers[i].opacite*100), Color.red(col), Color.green(col), Color.blue(col));
newbtn.getBackground().setColorFilter(newColor, MULTIPLY);
[COLOR="DarkOrange"]//applyFilter(newbtn, i, BlurMaskFilter.Blur.INNER);[/COLOR]
newbtn.setText("couche " + Integer.toString(i));
newbtn.setId(i);
newbtn.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,30+kwang07Android.layers[i].thickness/20));
final int finalI = i;
newbtn.setOnTouchListener(new Button.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
showColorPickerDialogDemo(newbtn, finalI);
}
return false;
}
});
lm.addView(newbtn);
}
...
Any advice?
Thanks.

How to draw or erase on a photo loaded onto a Imageview?

As what was stated on the header I want to implement either a "paint" function for user to edit paint/censor unwanted parts of a photo displayed on a imageview before uploading it to a server in the edited format and a redo function if user makes a mistake while editing?
How do I come about doing it, I've read relevant topics on Canvas, or FingerPaint but still puzzled on how to implement it based on my project here? Tried referencing to the links here and here but without success in implementing the codes into my project code due to my lack of programming skills.
Thanks for any help rendered!
