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.

I have an OnClickListener that listens to Button A clicks. I also have 2 TextViews below the Button.
I want that on every click on Button A, the 2 TextViews will switch their places between them, like this:
Before clicking:
TextView A
TextView B
After clicking:
TextView B
TextView A
How can I do it? Is there a special function that meant to do that? or some kind of a trick? Thanks!

}
}
}
View.bringToFront method may be useful.
Where your layout is like:
<LinearLayout>
<TextView A>
<TextView B>
</LinearLayout>
To call bringToFront on TextView A will bring it front (the last position in the parent LinearLayout).
<LinearLayout>
<TextView B>
<TextView A>
</LinearLayout>
For more detailed example, below is layout.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/text_holder"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<TextView
android:id="#+id/text_a"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text_a" />
<TextView
android:id="#+id/text_b"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text_b" />
</LinearLayout>
In your OnClickListener (in your Activity) call:
View textViewA = findViewById(R.id.text_a);
textViewA.bringToFront();
This should work.
Toggling behavior can be achieved by this application. For example:
ViewGroup textHolder = (ViewGroup) findViewById(R.id.text_holder);
textHolder.getChildAt(0).bringToFront();
ViewGroup.getChildAt(0) always returns the first child of the ViewGroup. So everytime you call bringToFront on the first child will be bring to front.
All previous answers do not work because you use a relative layout where a linear layout will suffice.
If you have to go RelativeLayout, do the following in your click listener
TextView textA = (TextView) findViewById(R.id.txtA);
TextView textB = (TextView) findViewById(R.id.txtB);
RelativeLayout.LayoutParams textALayoutParams = (RelativeLayout.LayoutParams) textA.getLayoutParams();
textALayoutParams.addRule(RelativeLayout.BELOW, R.id.txtB);
textA.setLayoutParams(textALayoutParams);
RelativeLayout.LayoutParams textBLayoutParams = (RelativeLayout.LayoutParams) textB.getLayoutParams();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
textBLayoutParams.removeRule(RelativeLayout.BELOW);
} else {
textBLayoutParams.addRule(RelativeLayout.BELOW,0);
}
textB.setLayoutParams(textBLayoutParams);
This will place A under B. You can do the same for reversing.
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

I want my seekbar having values from 33 to 80, I have read in Google, that we cannot set minimum in xml, so I add 33 to progress. But the thing is that my seekbar gets values from 33 to 113(max + 30). Any tips will be valuable for me, thank you.
TextView textView123;
SeekBar seekBar;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calc);
seekBar = (SeekBar) findViewById(R.id.seekBar1);
textView123 = (TextView) findViewById(R.id.progress);
textView123.setText(seekBar.getProgress() + " ");
seekBar.setOnSeekBarChangeListener(
new OnSeekBarChangeListener() {
int progress = 0;
#Override
public void onProgressChanged(SeekBar seekBar,
int progresValue, boolean fromUser) {
progress = progresValue + 33;
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
// Do something here,
}
#Override
public void onStopTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
textView123.setText(progress + " ");
}

Simple solution:
Set max to the actual value you want minus the min value you programmatically add in onProgressChanged.
In your case, simply set max to 47 (80 - 33).
When I first launch my app everything displays and works correctly but when I close and reopen it a spinner and button that sit next to each other at the top of my relative layout are only about half of their usual height and the spinner is unusable. If I click it nothing drops down (but the button works as usual). Other elements below the spinner and but display as usual.
I spent half the day googling and playing with the app code and layout XML and have made little to no progress.
Anyone got a clue as to what could be causing this? It only happens on subsequent runs of the app.

This should be the relevant parts of the main activity that call it:
public class MainActivity extends Activity {
static Spinner nameSpinner;
ArrayAdapter nameAdapter;
static ArrayList nameList;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override

super.onResume();
// get spinner and init array if needed
if (nameList == null) {
nameSpinner = (Spinner) findViewById(R.id.namespinner);

nameList.add("( Add )");
}
// populate spinner
nameAdapter = new ArrayAdapter(this,
android.R.layout.simple_spinner_dropdown_item, nameList);
nameSpinner.setAdapter(nameAdapter);
// listen for events/selections on the spinner
nameSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView parentView,
View selectedItemView, int position, long id) {
// read state
}
}
#Override
public void onNothingSelected(AdapterView parentView) {
// do I want to do anything here?
}
});
}
}
Edited to clean up the code display and add the class def. and class variables.
You have to insert the code wrote in the onresume method in oncreate method!
Setting the spinner in an if statement that didn't really have anything to do with setting the spinner was the cause of the problem. By changing this:
if (nameList == null) {
nameSpinner = (Spinner) findViewById(R.id.namespinner);
nameList = new ArrayList();
nameList.add("( Add )");
}
to
nameSpinner = (Spinner) findViewById(R.id.namespinner);
if (nameList == null) {
nameList = new ArrayList();
nameList.add("( Add )");
}
got it sorted.
A good nights sleep and fresh eyes where all that were needed. :P
I want to change the background image and TextView Color on click of a layout .The background color is chnaging properly but my textview color is not changing.Here is my XML code :
<RelativeLayout
android:id="#+id/flight_relative"
android:clickable="true"
android:layout_width="match_parent"
android:layout_height="70dp"
android:layout_below="#+id/imgLogo"
android:layout_marginTop="5dp"
android:background="#drawable/button_effect"
android:gravity="center_vertical" >
<TextView
android:id="#+id/flight_content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/flight_list_image"
android:layout_marginTop="10dp"
android:layout_toRightOf="#+id/flight_list_image"
android:text="#string/flight_tittle"
android:textColor="#152b72"
android:textSize="15dp"
android:textStyle="bold" />
<TextView
android:id="#+id/content_flight"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/flight_content"
android:layout_toRightOf="#+id/flight_list_image"
android:text="#string/flight_content"
android:textColor="#2f2f2f"
android:textSize="10sp" />
<ImageView
android:id="#+id/flight_arrow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/flight_content"
android:layout_alignParentRight="true"
android:src="#drawable/arrow" />
<ImageView
android:id="#+id/flight_list_image"
android:layout_width="50dip"
android:layout_height="50dip"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:padding="3dip"
android:src="#drawable/flight_icon" />
</RelativeLayout>
Code to chnage the textview color is :
flightRelative = (RelativeLayout )findViewById(R.id.flight_relative);
flightRelative.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
flight = (TextView)findViewById(R.id.flight_content);
flight.setTextColor(Color.WHITE);
}
});
What wrong i am doing please suggest me .For the first time it is not working on second time it is working
You should add this definitely working.I am also check it out...
flightRelative.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
TextView flight = (TextView)findViewById(R.id.flight_content);
flight.setTextColor(Color.parseColor("#FFFFFF"));
}
});
you should use
#Override
public void onClick(View arg0) {
flight = (TextView)flightRelative.findViewById(R.id.flight_content);
flight.setTextColor(Color.WHITE);
}
I believe it should work now.
