I want to add text inside switches and expect toggle to completely cover the texts
I was able to achieve this in API 16 with below option
<Switch
android:textOff="off"
android:showText="true"
android:textOn="on"/>
However same switch looks odd in the higher version(i'm testing with API 27) where switch toggle is a round icon behind the text.
Is there a way i can fit the text inside the switch toggle using native library/methods.
I found this code in GitHub. After some addition and modification, I get what I need. This toggle button has YES NO text on it and works like switch button. You can give it a go.

I want to create loader in android as same as attached gif
Thanks in advance
Without Plane in your Image I prefer to use ProgressBar
but I will Be More Easy to user SeekBar As Progress Bar
so let`s make it in Simplest way
in Layout XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:hardwareAccelerated="false"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<SeekBar
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:background="#32aaef"
android:id="#+id/sbHeight"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp"
android:max="100"
android:progress="0"
android:progressDrawable="#drawable/seekbar_as_progress"
android:thumb="#drawable/plane"
/>
</LinearLayout>
And where seekbar_as_progress is
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Define the background properties like color etc -->
<item android:id="#android:id/background">
<shape
android:shape="line"
android:useLevel="true">
<stroke
android:width="3dp"
android:color="#c9c9c9"
android:dashGap="20dp"
android:dashWidth="3dp" />
</shape>
</item>
<!-- Define the progress properties like start color, end color etc -->
<item android:id="#android:id/progress">
<clip>
<shape
android:shape="line"
android:useLevel="true">
<stroke
android:width="6dp"
android:color="#ffffff"
android:dashGap="20dp"
android:dashWidth="4dp" />
</shape>
</clip>
</item>
</layer-list>
and #drawable/plane is plane Icon
And In Your Activity
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// DountChart view = new DountChart(this);
setContentView(R.layout.empty);
final SeekBar sbHeight = findViewById(R.id.sbHeight);
sbHeight.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
sbHeight.setOnTouchListener(new View.OnTouchListener(){
#Override
public boolean onTouch(View v, MotionEvent event) {
return true;
}
});
final int[] progress = {0};
final Handler ha=new Handler();
ha.postDelayed(new Runnable() {
#Override
public void run() {
//call function
if (progress[0] != 100){
AppLogger.log("Prog",progress[0]+"");
progress[0]= progress[0]+1;
sbHeight.setProgress(progress[0]);
ha.postDelayed(this, 100);
}
}
}, 100);
}
and that`s All
I have a question, I have a seek bar and I want to show the buffer progress of an ExoPlayer media file using the secondary progress bar of the seekBar, the problem is that it´s not showing. Im running on API 21
Here´s the xml code:
<SeekBar
android:id="#+id/seekBarAudioA"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"
android:maxHeight="3dip"
android:minHeight="3dip"
android:progressDrawable="#drawable/seek_bar_progress"
android:secondaryProgressTint="#android:color/holo_blue_dark"
android:thumbTint="#color/amber"
app:layout_constraintBottom_toBottomOf="#+id/play_pause"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintLeft_toRightOf="#+id/play_pause"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="#+id/play_pause" />
and here´s the java code:
SeekBar = new Thread(new Runnable() {
#Override
public void run() {
try {
while (currentlyPlaying && currentAudioHolder.getAdapterPosition() == audioPosition) {
int duration = (int) exoPlayer.getDuration();
currentAudioHolder.seekBarAudio.setMax(duration);
currentAudioHolder.seekBarAudio.setSecondaryProgress((int) exoPlayer.getBufferedPosition());
final int currPosition = (int) exoPlayer.getCurrentPosition();
Log.d("Buffer", "secondary progress bar position is: " + (int) exoPlayer.getBufferedPosition() + ", and the current position is: " + currPosition);
currentAudioHolder.seekBarAudio.setProgress(currPosition);
((ChatActivity) context).runOnUiThread(new Runnable() {
#Override
public void run() {
currentAudioHolder.audioLength.setText(convertTime(currPosition));
}
});
Thread.sleep(sleep);
}
} catch (InterruptedException i) {
currentlyPlaying = false;
}
}
});
SeekBar.start();
Please help :(
I might be late, but here is my answer: you should check your seek_bar_progress file, that you use for android:progressDrawable, and see if it looks like this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#android:id/background">
<shape android:shape="rectangle">
<corners android:radius="2dp"/>
<solid android:color="#color/myBgColor"/>
</shape>
</item>
<item android:id="#android:id/secondaryProgress">
<scale android:scaleWidth="100%">
<shape android:shape="rectangle">
<corners android:radius="2dp"/>
<solid android:color="#color/myColor"/>
</shape>
</scale>
</item> <item android:id="#android:id/progress">
<clip>
<shape android:shape="rectangle">
<corners android:radius="2dp"/>
<solid android:color="#color/myColor"/>
</shape>
</clip>
</item>
</layer-list>
I found out that the part with the #android:id/secondaryProgress id was missing in my drawable, and that was the reason why it was not working for me.
Hope it helps.
I'm using RecyclerView to display a few resource-consuming images. My implementation looks like the following:
private class NoteConfigItemAdapter extends RecyclerView.Adapter<NoteConfigItemAdapter.NoteConfigViewHolder> {
public class NoteConfigViewHolder extends RecyclerView.ViewHolder {
private final ToggleButton tbButton;
private final TextView tvDescription;
private int index;
private final View.OnClickListener buttonClickListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
int oldSelectedItem = selectedItem;
selectedItem = index;
notifyItemChanged(oldSelectedItem);
notifyItemChanged(selectedItem);
}
};
public NoteConfigViewHolder(View itemView) {
super(itemView);
tbButton = (ToggleButton)itemView.findViewById(R.id.notesConfig_tbButton);
tvDescription = (TextView)itemView.findViewById(R.id.notesConfig_tvDescription);
tbButton.setOnClickListener(this.buttonClickListener);
}
public void setData(int descriptionResource, int drawableResource, int index) {
this.index = index;
tvDescription.setText(descriptionResource);
Drawable background = ResourcesCompat.getDrawable(getResources(), drawableResource, null);
tbButton.setBackground(background);
tbButton.setChecked(index == selectedItem);
}
}
private List<NoteConfigItem> configItems;
private int layoutResource;
private int selectedItem = 0;
public NoteConfigItemAdapter(List<NoteConfigItem> configItems, int layoutResource) {
this.configItems = configItems;
this.layoutResource = layoutResource;
}
#Override
public NoteConfigViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater
.from(parent.getContext())
.inflate(layoutResource, parent, false);
return new NoteConfigViewHolder(itemView);
}
#Override
public void onBindViewHolder(NoteConfigViewHolder holder, int position) {
NoteConfigItem item = configItems.get(position);
holder.setData(item.stringResource, item.drawableResource, position);
}
#Override
public int getItemCount() {
return configItems.size();
}
}
Single item's layout contains only ToggleButton and TextView:
I'm dynamically assigning background to the ToggleButton upon binding. Background is a Drawable, which defines two states for the button:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true">
<layer-list>
<item>

</shape>
</item>
<item>
<inset android:insetTop="#dimen/selectionBorderSize"
android:insetLeft="#dimen/selectionBorderSize"

</item>
</layer-list>
</item>
<item>
<shape android:shape="rectangle">
<solid android:color="#ffffff" />
</shape>
</item>
</selector>
#drawable/fullRange is a PNG image. Itself it is not so big (~hundred of such images occupy around 400kb), but it is quite big (225px x 450px), so I guess the bitmap object created from this PNG can be memory-costly.
When I run the application, I monitor the memory usage. When I only scroll through RecyclerViews, the chart looks like the following:
But when I start to select items, occupied memory starts to grow until OutOfMemoryException:
What am I doing wrong? Why arent the resources being reused/disposed?
I'm using XML drawables and overlaying them ontop of eachother dynamically using layers. Everytime the user hits a button it overlays another image. The issue is that once I have five or ten layers of this particular XML drawable then the UI wants to just lock up. Here is the drawable:
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<rotate
android:fromDegrees="247.5"
android:toDegrees="247.5"
android:pivotX="50%"
android:pivotY="50%">
<shape android:shape="oval">
<size
android:width="800dp"
android:height="800dp"/>
<stroke
android:dashWidth="235.6dp"
android:dashGap="5000.01dp"
android:width="200dp"
android:color="#c2272d" />
</shape>
</rotate>
</item>
<item android:top="0dp" android:bottom="0dp" android:left="0dp" android:right="0dp">
<rotate
android:fromDegrees="247.5"
android:toDegrees="247.5"
android:pivotX="50%"
android:pivotY="50%">
<shape android:shape="oval">
<size

android:height="800dp"/>
<stroke

android:dashGap="5000.01dp"
android:width="60dp"
android:color="#767171" />
</shape>
</rotate>
</item>
</layer-list>
And here is the code I am using to display and update:
public class ShotMagFragment extends Fragment implements DataDelegate, View.OnClickListener{
private ImageView mainImage;
private ArrayList<Drawable> layers = new ArrayList<>();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_shot_mag, container, false);
View simulateBtn = view.findViewById(R.id.simulateBtn);
simulateBtn.setOnClickListener(this);
mainImage = (ImageView)view.findViewById(R.id.mainImage);
return view;
}
public void displayNewImage() {
Random r = new Random();
int number = 1 + (20 - 20) * r.nextInt();
Drawable d = getResources().getDrawable(getResources().getIdentifier("mag_shade" + number, "drawable", getContext().getPackageName()));
layers.add(d);
final LayerDrawable layerDrawable = new LayerDrawable(layers.toArray(new Drawable[layers.size()]));
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
mainImage.setImageDrawable(layerDrawable);
}
});
}
#Override
public void onClick(View v) {
displayNewImage();
}
}
But when I use a different XML drawable I don't get the same UI lock up problem:
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="130dp" android:bottom="130dp" android:left="130dp" android:right="130dp">
<rotate
android:fromDegrees="247.5"
android:toDegrees="247.5"
android:pivotX="50%"
android:pivotY="50%">
<shape android:shape="oval">
<size
android:width="540dp"
android:height="540dp"/>
<stroke
android:dashWidth="212.0dp"
android:dashGap="5000.01dp"
android:width="4dp"
android:color="#fff" />
</shape>
</rotate>
</item>
</layer-list>
EDIT
I also get a weird error icon next to my reference to my drawable. When I click on it, it just takes me to the drawable. I have no idea if that is related to my problem, if it is a real error, or if it is just a notice.
I have a custom ImageButton class mimicing the ToggleButton's checked state based on this tutorial How to add a custom button state .
Everything works fine, when I have a state list drawable as the android:src attribute, but the custom state doesn't work with the ImageButton's android:background attribute.
Here is my code:
import android.content.Context;
import android.util.AttributeSet;
import android.widget.Checkable;
import android.widget.ImageButton;
public class CheckableImageButton extends ImageButton implements Checkable {
private static final int[] STATE_CHECKED = {R.attr.state_checked};
private boolean mChecked = false;
public CheckableImageButton(Context context) {
super(context);
}
public CheckableImageButton(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
public int[] onCreateDrawableState(int extraSpace) {
final int[] drawableState = super.onCreateDrawableState(extraSpace + 1);
if(mChecked){
mergeDrawableStates(drawableState, STATE_CHECKED);
}
return drawableState;
}
#Override
public boolean isChecked() {
return mChecked;
}
#Override
public void setChecked(boolean checked) {
mChecked = checked;
refreshDrawableState();
}
#Override
public void toggle() {
setChecked(!mChecked);
}
}
And the relevant snippet from the layout XML:
<com.my.package.view.CheckableImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:background="#drawable/header_button_bg"
android:padding="5dp"
android:src="#drawable/menu_button"
tools:ignore="ContentDescription" />
And the state list drawable:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res/my.package" >
<item android:state_pressed="true">
<shape android:shape="rectangle">
<stroke android:width="1dp" android:color="#ff000000" />
<gradient android:angle="-90" android:endColor="#d2914e" android:startColor="#906434" />
<corners android:radius="5dp" />
</shape>
</item>
<item app:state_checked="true">
<shape android:shape="rectangle">
<stroke android:width="1dp" android:color="#ff000000" />
<gradient android:angle="-90" android:endColor="#d2914e" android:startColor="#906434" />
<corners android:radius="5dp" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<stroke android:width="1dp" android:color="#ff000000" />
<gradient android:angle="-90" android:endColor="#4f5b6c" android:startColor="#345b75" />
<corners android:radius="5dp" />
</shape>
</item>
</selector>
Another wonderful trait of eclipse probably..
When I tried to revert my code to the last working version by hand (the state list drawable in the android:src tag), it produced the same error. I reverted from the SVN repo, it worked. Then I made the exact same changes as before, character by character, no difference, and voilá, it works now!
So that's it, the code in the question is fully functional.
