Adjust the size of a shape based on seekbar progress

I currently am trying to use the SeekBar to change the size of a ring: as the value of the SeekBar increases, I would like the size of the ring to increase. However, when I use the code below, the shape size does not change. Does anyone know how to make this work?
public class MainActivity extends Activity {
TextView textview3;
SeekBar tipSeekBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tipSeekBar = (SeekBar) findViewById(R.id.seekBar);
tipSeekBar.setOnSeekBarChangeListener(tipSeekBarListener);
}
private OnSeekBarChangeListener tipSeekBarListener = new OnSeekBarChangeListener(){
#Override
public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {
TextView textview3 = (TextView) findViewById(R.id.textView3);
textview3.setHeight((int) (tipSeekBar.getProgress()));
textview3.setWidth((int) (tipSeekBar.getProgress()));
}
#Override
public void onStartTrackingTouch(SeekBar arg0) {
TextView textview3 = (TextView) findViewById(R.id.textView3);
textview3.setHeight((int) (tipSeekBar.getProgress()));
textview3.setWidth((int) (tipSeekBar.getProgress()));
}
#Override
public void onStopTrackingTouch(SeekBar arg0) {
TextView textview3 = (TextView) findViewById(R.id.textView3);
textview3.setHeight((int) (tipSeekBar.getProgress()));
textview3.setWidth((int) (tipSeekBar.getProgress()));
}
};

Your problem is here...
<TextView
android:id="#+id/textView3"
android:layout_width="200dp" <---
android:layout_height="200dp" <---
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="#drawable/ring_unfilled_gray" />
You've set the size explicitly, so it seems it won't override it as it would min, max(s), and wrapping content.
This works for me (changing the size of the text view via the seek bar that is)...
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content" <---
android:layout_height="wrap_content" <---
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="I'll get bigger soon..." /> <-- notice no background!
However, this is a hack. A text view probably isn't what you want. I didn't use an image because the image isn't important to controlling the height and width of the text view. An image would be more appropriate I believe. I think you'll find, once you get it "working", it might not behave as you would like.
Also -
You could be doing some unnecessary things here. My code that handles the progress change is like so (names changed to mine now)...
...
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if (fromUser) {
mTextView.setHeight(progress);
mTextView.setWidth(progress);
}
}
...
As you can tell I don't...cast an int to an int, getProgress() - I've already got it, or instantiate a new TextView for each change and gesture. You're actually allocating two new TextViews on a gesture; one at the start, and one at the end. You may want to keep a member TextView to hang on to and refer to the Android Docs to know what API methods you're using are doing, the parameters they provide, and their proper usage.

Android allow multi-touch on an activity

I am trying to allow the user to put a ring on the circle on the screen and then press the larger button so that the circle goes to the next ring size.
Everything work fines when no ring is on the screen.
However when a ring it on the screen no other touches are called and the buttons and the seekbar does not work.
I'm new in android and i haven't came across this requirement before. Is there a way I can allow multi-touch gestures on the activity or a way to ignore touches on that specific layout?

There is a way to ignore touches in particular layout,for that you should add
android:splitMotionEvents="false"
in your layout . You can refer answers from thie following link

Android screen resolution issue

I have two tablets. I have run a test resolution app to get screen parameters. Thouse are the results.
1) Coby MID7042 7": low density, scale: 0.75, 120dpi, 480 x 764,
layout for large screen, drawable LDPI.
2) BQ Elcano 7": high density, scale: 1.5, 240dpi, 800 x 1208, layout
for large screen, drawable HDPI.
I have developed an android application that fits good on Coby screen, but in BQ the screen is cut in the right and in the bottom. That is, the screen is bigger than you can see on the screen. I think BQ screen is better and bigger than Coby, but I don't know why it doesn't fit the screen.
In my developed android app, the xml file for the screen is into res/layout folder. I always use sp and dp.
I have read about "supporting multiple screen" and so on, but in this case, I think BQ should show the screen at right fit using the same layout. But it doesn't.
Some one could help me about this issue? I don't know how could I solve this, because two tablets are large for layouts.
Thanks.
Edited. This is a layout that is cut in the right (the latest EditText is cut):

DroidUsers answer is little bit confusing but method is effective...
look for more effective example:

I have Used one approach where I design the Layout I wanted in a standard device, and store all dynamically apply all the layout dependent values(eg: padding, margin etc) using a seperate class. And by calculating a ratio with current device config to the standard i have stored,
I will give you my sample code. just go through it and find your way accordingly

You should try to work with android:layout_weight instead of specifying your LinearLayout's android:layout_width="130dp". This way, the widths of your textviews and edittexts and what not can be set to fill_parent and Android will scale anything to the size of your screen, whatever the device you're working on might be.
With an exception for the linear layout where you have a new linearlayout for the edittext and a button, there you should use the weight attribute for this edittext and button again instead of their width parameters.
A slightly modified (I couldn't keep the style and text attributes when testing, for obvious reasons) example of how your xml would look:
<LinearLayout

android:layout_height="wrap_content"
android:layout_marginTop="5dp"

After lot of sarch I haven't found why it happens, but a very quickly solution. I can scale all the application adding this code to the main activity:
public void changeDensity(float desiredDensity) {
//desiredDensity : ldpi = 0.75 (120dpi) , mdpi = 1 (160dpi), hdpi = 1.5 (240dpi), xhdpi = 2.0 (320dpi)
DisplayMetrics metrics = getResources().getDisplayMetrics();
metrics.density = desiredDensity;
metrics.xdpi = desiredDensity * 160;
metrics.ydpi = desiredDensity * 160;
metrics.densityDpi = (int) (desiredDensity * 160);
getResources().updateConfiguration(null, null);
}
Calling this function on creating main activity, with 1.25f as desiredDensity, the application is scaled to fit the right dimension. I know this isn't the rigth way. I should change all layout, but I can't do it with this device because both use the same layout (large) and then, perhaps, I should use w as parameter in res/layout. Briefly, scaling resolve the problem.

Android Activity as dialog black border

I have activity as a dialogue, all the shows I like. But I have a problem with a frame around them. Just like here.
My Activity:
public class AlarmAlert extends Activity implements Alarms.AlarmSettings {
#Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
AlarmAlertWakeLock.acquire(this);
/*
* FIXME Intentionally verbose: always log this until we've fully
* debugged the app failing to start up
*/
Log.v("AlarmAlert.onCreate()");
DigitalClock dc = (DigitalClock) findViewById(R.id.digitalClock1);
mKeyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
Intent i = getIntent();
mAlarmId = i.getIntExtra(Alarms.ID, -1);
Alarms.getAlarm(getContentResolver(), this, mAlarmId);
mKlaxon = new AlarmKlaxon();
mKlaxon.postPlay(this, mAlarmId);
/* Set the title from the passed in label */
setTitleFromIntent(i);
/*
* allow next alarm to trigger while this activity is active
*/
Alarms.disableSnoozeAlert(AlarmAlert.this);
Alarms.disableAlert(AlarmAlert.this, mAlarmId);
Alarms.setNextAlert(this);
mKlaxon.setKillerCallback(new AlarmKlaxon.KillerCallback() {
public void onKilled() {
if (Log.LOGV)
Log.v("onKilled()");
updateSilencedText();
/* don't allow snooze */
mSnoozeButton.setEnabled(false);
dismiss();
mState = KILLED;
}
});
updateLayout();
SharedPreferences settings = getSharedPreferences(
AlarmClock.PREFERENCES, 0);
if (settings.getBoolean(AlarmClock.PREF_SHAKE_SNOOZE, true)) {
mShakeListener = new ShakeListener(this);
mShakeListener
.setOnShakeListener(new ShakeListener.OnShakeListener() {
public void onShake() {
snooze();
if (mCaptchaSnooze == 0)
finish();
}
});
}
}
private void setTitleFromIntent(Intent i) {
mLabel = i.getStringExtra(Alarms.LABEL);
if (mLabel == null || mLabel.length() == 0) {
mLabel = getString(R.string.default_label);
}
setTitle(mLabel);
}
private void updateSilencedText() {
TextView silenced = (TextView) findViewById(R.id.silencedText);
silenced.setText(getString(R.string.alarm_alert_alert_silenced,
mDuration / 1000 * 60));
silenced.setVisibility(View.VISIBLE);
}

How do I remove the border.

dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
Dialog

You have two options. You can set the theme of your Activity to
Theme_Translucent_NoTitleBar
Or you have to create a new theme and load it with a custom nine patch as specified here

android RelativeLayout how to get smaller size window

I cannot get the Theme.Dialog activity to get smaller.
The problem is that i want half the hight only.
Look at the picture down below.
Here is the manifest:
<activity android:name=".PopUpSettings"
android:label="#string/app_name"
android:theme="#android:style/Theme.Dialog"
android:screenOrientation="portrait"
android:configChanges="keyboardHidden|orientation">
here is the xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="15dp"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:paddingBottom="15dp"

<com.hellberg.ptppservice.imageedit.ColorPicker

android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
/>
</RelativeLayout>
Here is the screen:

This will do what you want. Be aware that you'll get the full window height so dividing with 2 wont make it exactly half the size. I tried your layout dividing with 3 and it looks good.
public class DialogExampleActivity extends Activity {
private int mWindowHeight;
private static final int DIALOG_OPEN = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Display display = getWindowManager().getDefaultDisplay();
mWindowHeight = display.getHeight();
showDialog(DIALOG_OPEN);
}
#Override
protected Dialog onCreateDialog(int id) {
Dialog myDialog = new Dialog(DialogExampleActivity.this);
switch (id) {
case DIALOG_OPEN:
myDialog.setContentView(R.layout.my_dialog);
myDialog.setCancelable(true);
RelativeLayout rr = (RelativeLayout) myDialog.findViewById(R.id.relative_layout);
LayoutParams params = rr.getLayoutParams();
params.height = mWindowHeight / 3;
rr.setLayoutParams(params);
return myDialog;
}
return null;
}
}
