Make custom EditText numeric-only

I have a custom EditText which I got from here.
PROBLEM: This by default, opens the normal keyboard. I want to open the numeric keyboard. I tried adding inputType="number" in the XML, but then it stops showing the placeholder lines.
How can I make this open the numeric keyboard while still showing the placeholder lines ?
Also, how is it possible to set maxLength from inside the class ?
Below is the code:
public class PinEntryEditText extends android.support.v7.widget.AppCompatEditText {
public static final String XML_NAMESPACE_ANDROID = "http://schemas.android.com/apk/res/android";
private float mSpace = 10; //24 dp by default, space between the lines
private float mCharSize;
private float mNumChars = 6;
private float mLineSpacing = 8; //8dp by default, height of the text from our lines
private int mMaxLength = 6;
private int pinLength;
private OnClickListener mClickListener;
private float mLineStroke = 1; //1dp by default
private float mLineStrokeSelected = 2; //2dp by default
private Paint mLinesPaint;
int[][] mStates = new int[][]{
new int[]{android.R.attr.state_selected}, // selected
new int[]{android.R.attr.state_focused}, // focused
new int[]{-android.R.attr.state_focused}, // unfocused

XML:
<com.mridulahuja.kudamm.tools.PinEntryEditText
android:id="#+id/txtToken"
android:layout_width="0dp"
android:layout_height="55dp"
android:ems="10"
pin:pinLength="6"
android:gravity="center"
app:layout_constraintTop_toTopOf="parent"
android:layout_marginTop="8dp"
app:layout_constraintRight_toRightOf="parent"
android:layout_marginRight="15dp"
android:layout_marginEnd="15dp"
android:layout_marginLeft="15dp"
android:layout_marginStart="15dp"
app:layout_constraintLeft_toLeftOf="parent"/>

Default length is set from code:
private int mMaxLength = 6;
But this library reads value from xml too:
mMaxLength = attrs.getAttributeIntValue(XML_NAMESPACE_ANDROID, "maxLength", mMaxLength);
so you can use both approaches.
In order to make placeholders visible you should add the _ symbol like this:
android:digits="0123456789_"
May be you'll need to add some other symbols, based on your needs.

Compound child view not shown inside custom ViewGroup

I'm coding a ring menu that is going to put together several different types of view, which will have all the same size. The thing is that it works perfectly with native views, like ImageView, but when I try to put a custom labeled image view, it simply doesn't appear int the custom ViewGroup. It's also worth mentioning that when this view is declared in the XML file, outside de custom ViewGroup it is shown just fine, but as soon as I put it inside the ViewGroup, or declare it programatically, it vanishes. My guess is that I'm doing something weong inside the onLayout method, but I can't put my finger on it, since all coordinates and view sizes are correct according to the Log.
The XML file for the CompoundView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:focusable="true">
<ImageView
android:id="#+id/header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:src="#drawable/ropeiconselector"/>
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="WWWWWWWWWWWW"
android:background="#color/button"
android:layout_marginLeft="-10dp"
android:layout_centerVertical="true"
android:layout_toRightOf="#id/header"
android:padding="8dp"
/>
The code for the CompoundView (I omitted some unimportant methods)
public class CircularLabeledImageView extends RelativeLayout implements View.OnClickListener {
ImageView headerView;

boolean isOpen = false;

int position;

Bullet points in textview are cut off

I have a TextView in an app, the text of which is set by a hard-coded string resource in the layout. In order to get a bulleted list in the TextView, I've used the (unofficial?) support for the <li> element. This creates properly-indented bullets, as desired, but the leftmost edge of the bullets themselves are slightly cut off, as you can see:
I have tried adding left padding to these, but it did nothing to the clipped edge - just moved the whole thing inwards.
Is there any simple solution to resolve this?
Where does the resource for that bulleted list live?

Old question but for anyone else finding this late:
I've found the built in BulletSpan class has had bugs from early android versions all the way through to marshmallow:
Bullet radius and gap width don't scale depending on dp
Bullets are sometimes cut off (should be + BULLET_RADIUS, not * BULLET_RADIUS)
Warning: I've seen a few custom BulletSpan classes out there which implement ParcelableSpan like the internal class. This WILL cause crashes and is not intended to be used externally.
Here's my BulletSpanCompat:
public class BulletSpanCompat implements LeadingMarginSpan {
private final int mGapWidth;
private final boolean mWantColor;
private final int mColor;
private static final int BULLET_RADIUS = MaterialDesignUtils.dpToPx(1.5f);
private static Path sBulletPath = null;
public static final int STANDARD_GAP_WIDTH = MaterialDesignUtils.dpToPx(8);
public BulletSpanCompat() {
mGapWidth = STANDARD_GAP_WIDTH;
mWantColor = false;
mColor = 0;
}
public BulletSpanCompat(int gapWidth) {
mGapWidth = gapWidth;
mWantColor = false;
mColor = 0;
}
public BulletSpanCompat(int gapWidth, int color) {
mGapWidth = gapWidth;
mWantColor = true;
mColor = color;
}
public BulletSpanCompat(Parcel src) {
mGapWidth = src.readInt();
mWantColor = src.readInt() != 0;
mColor = src.readInt();
}
public int getLeadingMargin(boolean first) {
return 2 * BULLET_RADIUS + mGapWidth;
}
public void drawLeadingMargin(Canvas c, Paint p, int x, int dir,
int top, int baseline, int bottom,
CharSequence text, int start, int end,
boolean first, Layout l) {
if (((Spanned) text).getSpanStart(this) == start) {
Paint.Style style = p.getStyle();
int oldcolor = 0;
if (mWantColor) {
oldcolor = p.getColor();
p.setColor(mColor);
}
p.setStyle(Paint.Style.FILL);
if (c.isHardwareAccelerated()) {
if (sBulletPath == null) {
sBulletPath = new Path();
// Bullet is slightly better to avoid aliasing artifacts on mdpi devices.
sBulletPath.addCircle(0.0f, 0.0f, 1.2f + BULLET_RADIUS, Path.Direction.CW);
}
c.save();
c.translate(x + dir + BULLET_RADIUS, (top + bottom) / 2.0f);
c.drawPath(sBulletPath, p);
c.restore();
} else {
c.drawCircle(x + dir + BULLET_RADIUS, (top + bottom) / 2.0f, BULLET_RADIUS, p);
}
if (mWantColor) {
p.setColor(oldcolor);
}
p.setStyle(style);
}
}
}

android:ellipsize="end" , "..." centered vertically

I have a weird problem, for some reason the android:ellipsize="end" works, but added the point in the middle of the text == centered vertically instead of being aligned to baseline:
I checked for any "center" properties, but there is none of those:
Update:
This is the XML part:
<com.citylifeapps.cups.customviews.CarmelaTextView
android:id="#+id/venue_address"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/venue_distance"
android:layout_toRightOf="#+id/venue_name"
android:gravity="left"
android:text="#string/placeholder_venue_address"
android:textColor="#color/cups_white"
android:textSize="20sp"
android:textStyle="bold"
android:ellipsize="end"
android:singleLine="true"
android:scrollHorizontally="true"
android:layout_alignBaseline="#+id/venue_name" />
And the custom TextView class:
public class CarmelaTextView extends TextView {
public CarmelaTextView(Context context, AttributeSet attrs) {
super(context, attrs);
setCarmelaTypeface(context);
}
public CarmelaTextView(Context context) {
super(context);
setCarmelaTypeface(context);
}
private void setCarmelaTypeface(Context context) {
if (this.isInEditMode()) return;
Typeface typeface = Typeface.createFromAsset(context.getAssets(), "carmela.ttf");
this.setTypeface(typeface);
}
}
further check shows that if I use a simple TextView the problem disappears,
but there is nothing in the custom TextView that will cause such a behavior.
Does anyone know why this might happen?
Thanks.

It looks like the problem lies within my custom font I'm using for this custom TextView, from the accepted answer here:
Why does TextView in single line elipsized with "end" show boxes?
I'm guessing that I'm facing the same problem but with a different result because the 3 dots (...) U+FEFF glyph for my font is different.
But still if some one found a solution that works for this issue I would be glad if he could share it.

As indicated above, checkMarkDrawable is Gravity position in the Canvas to determine the location.
My question is: How can change checkMarkDrawable the location, for example to set checkMarkDrawable in a TextView on the left.

If you want the checkbox to be on the left, simply just use a CheckBox. Maybe it is not matter of course, but a CheckBox can contain text. You can define that text by adding an XML attribute android:text, or by calling the setText() method. Actually CheckBox is inherited from Button, which inherits from TextView, that's why it has all the text-related properties.

Use drawableRight instead of checkMarkDrawable in xml.
