Android how to draw shape centered in view

I have multiple instances of a custom view where I'm trying to draw custom shapes using the center values from the view. The problem is that I've been unsuccessful when trying to get the center and drawing shapes on it, here is the result from the code below, you can see that the black squares are not properly centered in each one of the 4 squares:
class MyCustomView
constructor(context: Context,
attrs: AttributeSet? = null
) : View(context, attrs) {
private var center = PointF(0f, 0f)
override fun onSizeChanged(w: Int, h: Int, oldw: Int, oldh: Int) {
center.set(w / 2f, h / 2f)
}
override fun onDraw(canvas: Canvas) {
val squareDimension = 100F
val halfDimension = squareDimension / 2
if (center.x == 0F || center.y == 0F) {
center = PointF(width / 2F, height / 2F)
}
val paint = Paint()
paint.color = Color.rgb(
0,
0,
0)
canvas.drawRect(
center.x - halfDimension,
center.y - halfDimension,
center.x + halfDimension,
center.y + halfDimension,
paint)
}
}

How can I draw the shape properly in the center of each view?

If you look at your views, MyCustomView and its parent are set to wrap_content. It is also the LinearLayouts whose bounds you see in the screen. If you inspect your views, it's likely that MyCustomViews are not actually where you expect.
Your options:
Make LinearLayout widths and heights 0dp (though from the constraints this isn't required) and make MyCustomView widths and heights match_parent.
Remove LinearLayouts altogether and replace them with MyCustomView. The parent is currently redundant, though you may have a use for it later on.
In terms of your class, things look good, though I would have a single pointf only (val), create the paint globally and not on each draw, and avoid mutating the point during onDraw. You can optionally compute a RectF during onSizeChanged and avoid any further computation during onDraw

How to set android:drawable to left and top?

I just wanted to set icon to the top and left corner of my TextView.
This is my code and the output respectively:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Content"
android:drawableLeft="#drawable/icon" />
Output:
but I want to set my icon to the top and left like this one :

For this purpose you have to take the seperate imageView like this and in textview field you have to add one line code that android:layout_toRightOf="#+id/imageView":
For better understanding see following code:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView"
android:background="#mipmap/ic_launcher"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/imageView"
android:text="this si fodfjkhsdhaffjsdfasdfjhsdfhjsdhfjhsdfhsdhfhdsjfhsdjhfjhdsfhsdhfjhsdjhfjsdhfjhsdjfhjsdhfjhsdjfhjdshfsdjhfjsdhfsdkjhfjsdhfjhsdjfhjsdhjfhsdjhfjsdhfjhjsdhfjsdhjfhsdjf"
/>
</RelativeLayout>

Use below code;
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Content"
android:drawableTop="#drawable/def"
android:drawableLeft="#drawable/icon" />

You can align a compound-Drawable to the top (or bottom) by creating a custom Drawable that wraps your Drawable.
Usage
GravityCompoundDrawable gravityDrawable = new GravityCompoundDrawable(innerDrawable);
// NOTE: next 2 lines are important!
innerDrawable.setBounds(0, 0, innerDrawable.getIntrinsicWidth(), innerDrawable.getIntrinsicHeight());
gravityDrawable.setBounds(0, 0, innerDrawable.getIntrinsicWidth(), innerDrawable.getIntrinsicHeight());
textView.setCompoundDrawables(gravityDrawable, null, null, null);
Custom GravityCompoundDrawable class:
public class GravityCompoundDrawable extends Drawable {
// inner Drawable
private final Drawable mDrawable;
public GravityCompoundDrawable(Drawable drawable) {
mDrawable = drawable;
}
#Override
public int getIntrinsicWidth() {
return mDrawable.getIntrinsicWidth();
}
#Override
public int getIntrinsicHeight() {
return mDrawable.getIntrinsicHeight();
}
#Override
public void draw(Canvas canvas) {
int halfCanvas= canvas.getHeight() / 2;
int halfDrawable = mDrawable.getIntrinsicHeight() / 2;
// align to top
canvas.save();
canvas.translate(0, -halfCanvas + halfDrawable);
mDrawable.draw(canvas);
canvas.restore();
}
}

You can use setCompoundDrawablesWithIntrinsicBounds(int left, int top, int right, int bottom)

try this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="hello world"
android:layout_toEndOf="#+id/imageView" />
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_error" />
</RelativeLayout>

None of the solutions from SO worked form me. In the end I did it like this:
class MyTextView #JvmOverloads constructor(context: Context, attrs: AttributeSet? = null
) : AppCompatTextView(context, style) {
private val leftDrawable = ContextCompat.getDrawable(context, R.drawable.checkmark)
override fun onDraw(canvas: Canvas?) {
super.onDraw(canvas)
setBulletPoint(compoundDrawables[0], canvas)
}
private fun setBulletPoint(drawableLeft: Drawable?, canvas: Canvas?) {
if (!TextUtils.isEmpty(text)) {
leftDrawable?.let { drlft ->
if (lineCount == 1) {
setCompoundDrawablesWithIntrinsicBounds(drlft, null, null, null)
} else {
val buttonWidth = drlft.intrinsicWidth
val buttonHeight = drlft.intrinsicHeight
val topSpace = abs(buttonHeight - lineHeight) / 2
drlft.setBounds(0, topSpace, buttonWidth, topSpace + buttonHeight)
canvas?.apply {
save()
drlft.draw(canvas)
restore()
}
}
}
}
}
}

If you want to resolve it using compound drawable, you should create a custom textview and use it.
import android.content.Context
import android.graphics.Canvas
import android.util.AttributeSet
import androidx.appcompat.widget.AppCompatTextView
class TopAlignCompoundDrawableTextView: AppCompatTextView {
constructor(context: Context) : super(context)
constructor(context: Context, attrs: AttributeSet) : super(context, attrs)
constructor(context: Context, attrs: AttributeSet, defStyle: Int) : super(
context,
attrs,
defStyle
)
override fun dispatchDraw(canvas: Canvas?) {
super.dispatchDraw(canvas)
val centerTextView = height / 2
val drawableLeft = compoundDrawables[0]
drawableLeft?.let {
val topDrawable = it.intrinsicHeight/2 - centerTextView
it.setBounds(
0,
topDrawable,
it.intrinsicWidth,
it.intrinsicHeight + topDrawable
)
}
val drawableRight = compoundDrawables[2]
drawableRight?.let {
val topDrawable = it.intrinsicHeight/2 - centerTextView
it.setBounds(
0,
topDrawable,
it.intrinsicWidth,
it.intrinsicHeight + topDrawable
)
}
}
}

EditText and Horizontal Line

When we type an input value by using EditText, I want a horizontal line to be placed below my input like phone book application in all mobile phones.
Enter Phone : ___________
I want my input to be placed on this line. How can I do this by using EditText ?

Try this
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="2dp"
android:layout_marginTop="2dp">
<EditText
android:id="#+id/Prac"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Practice"
android:inputType="text"
android:textSize="12sp" />
</android.support.design.widget.TextInputLayout>

You have to set width of EditText from match_parent to wrap_content line below code
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>

You have to set width to either match_parent or to fixed width like 100dp
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>

As everyone answer said set width and height to wrap_content this is the right answer but still their is another way to achieve this lets have a look.
First create a drawable file (myline.xml) which create the line.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="1dp"
android:left="-2dp"
android:right="-2dp"
android:top="-2dp">
<shape android:shape="rectangle">
<stroke
// You can change width according to your need
android:width="1dp"
android:color="#000000" />
</shape>
</item>
Now in your layout.xml use myline.xml in edit text background.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Enter Phone: "
android:textColor="#000"
android:textSize="18dp" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/myline"
android:textColor="#000"
android:textSize="18dp" />
</LinearLayout>
And its done see the output in screenshot below.

You can Try with CustomEditText Like Below code:
package com.cj.myapplication;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Rect;
import android.util.AttributeSet;
import android.widget.EditText;
/**
* Created by E069099 on 7/20/2017.
*/
public class CustomEdiTextWithLine extends EditText {
private Rect rect;
private Paint paint;
public CustomEdiTextWithLine(Context context, AttributeSet attrs) {
super(context, attrs);
rect = new Rect();
paint = new Paint();
paint.setStyle(Paint.Style.FILL);
paint.setColor(Color.GREEN);
paint.setStrokeWidth(2F);
paint.setStrokeCap(Paint.Cap.ROUND);
paint.setTextSize(20);
}
#Override
protected void onDraw(Canvas canvas) {
//start at the vertical center of the textview
float top = (getHeight() + getPaddingTop() - getPaddingBottom())/2;
//start at the left margin
float left = getPaddingLeft();
//we draw all the way to the right
float right = getWidth() -getPaddingRight();
//we want the line to be 2 pixel thick
float bottom = getHeight()- getPaddingBottom();
canvas.drawLine(0,bottom,right,bottom,paint);
super.onDraw(canvas);
}
}

one method is,
make backgroundtint is black colour and set hint like below code
<EditText
android:layout_width="200dp"
android:layout_height="wrap_content"
android:backgroundTint="#000000"
android:hint=" " />
other method is,
add a view with black background below the editText and background of the editText is make it null.

How to center the checkbox and text of checkedTextView in android?

I have activity_choose_number1.xml

</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_choose_number1" />
This is content_choose_number1.xml
<?xml version="1.0" encoding="utf-8"?>

This is secnumsinglechoice.xml
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"

tools:targetApi="ice_cream_sandwich"
android:textSize="25dp"
android:linksClickable="false"
android:checked="false"
android:paddingTop="20dp"
android:paddingBottom="20dp" />
The secnumsinglechoice.xml is copy paste of android.R.layout.simple_list_item_single_choice and made some changes.
Now what I need is to center align the checkbox and text of secnumusingchoice.xml. I also need the checkbox to be left side of text in each item of list view
Things I tried
1) If I do drawableLeft, it creates space between text and checkbox, but doesn't make both to be centered
2) If I add android:textAlignment="center" then still it center aligns the text but not the check box .
3) I tried here center text and checkmark of CheckedTextView but I would like to try here with more code.
Please help. Thanks.

Is that what you want
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#android:color/white"
android:gravity="center">
<CheckBox
android:id="#+id/ckb"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true" />
<TextView
android:id="#+id/tvEduName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="ABC"
android:textSize="17sp" />
</LinearLayout>
Result

To get everything to center correctly, we'll subclass CheckedTextView, and override its onDraw() method to first measure the combined Drawable and text widths and paddings, and then translate the Canvas accordingly before calling the super method to actually do the draw.
import android.content.Context;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.widget.CheckedTextView;
import android.text.Layout;
public class CenteredCheckedTextView extends CheckedTextView {
public CenteredCheckedTextView(Context context) {
this(context, null);
}
public CenteredCheckedTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onDraw(Canvas canvas) {
if (getCompoundDrawables()[0] == null) {
super.onDraw(canvas);
}
else {
// Left drawable and paddings width
final float dw = getCompoundDrawables()[0].getIntrinsicWidth() +
getPaddingLeft() + getCompoundDrawablePadding();
// Text width
final float tw = getMaxLineMeasure();
canvas.save();
canvas.translate((getWidth() - (dw + tw)) / 2f, 0f);
super.onDraw(canvas);
canvas.restore();
}
}
private float getMaxLineMeasure() {
final Layout layout = getLayout();
final int lines = getLineCount();
float m = 0, max = 0;
for (int i = 0; i < lines; ++i) {
m = getPaint().measureText(getText(),
layout.getLineStart(i),
layout.getLineEnd(i));
if (m > max) {
max = m;
}
}
return max;
}
}
CheckedTextView has a checkMarkGravity attribute that determines on which end it places the checkMark Drawable, but it's not public, for some odd reason, so we'll just use the drawableLeft. For example:
<com.mycompany.myapp.CenteredCheckedTextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="20dp"
android:paddingBottom="20dp"
android:textSize="25dp"
android:drawableLeft="?android:attr/listChoiceIndicatorSingle" />
You might need to slightly fiddle with the translation and/or width values in the custom class to get everything to line up with what looks centered to you, depending on what kind of transparent, intrinsic padding the Drawable has.

Whatsapp Message Layout - How to get time-view in the same row

I was wondering how WhatsApp handles the time shown in every message.
For those who don't know:
If the message is very short, the text and time are in the same row.
If the message is long, the time is in the bottom right corner - the text wrapped around it.
With a RelativeLayout and toLeftOf I would get 1) but not 2) as previous lines would be "cut off" at the position of the time view. Same behaviour If i use a LinearLayout.
So I tried to use a FrameLayout or a RelativeLayout without any connection between text and time.
However, if the text is as long as the message-view is big, both views would overlap.
If I put blank characters to my message I wouldn't have the time on the right.
Do they really have some kind of text-wrapping-lib for this or is it possible to do only with layouts?
Here is the requested screenshot:

#Hisham Muneer 's answer very good.
But there are some problems. For example:
If the TextView has 2 full lines (end to end), the text will
intersect with datetime text layout. Finally, the views will
look like onion effect.
The text line wraps can't works efficiently. You must control this
lines and relocate the datetime view.
I'm going to share my solution, if you will need like this problem.

You can modify layout xml and some sections related your scenario.
There are 2 important point: you must define in layout xml "viewPartMain", "viewPartSlave" attributes. Because the code will decide measure via your main(chat textview) and slave(datetime text view) elements.
I wish have good days. Greets.

Adding HTML non-breaking spaces did the trick. Tested the code on most devices and working absolutely fine. Maybe whatsapp is also doing the same thing. Below is the chat code:
See images below to see it working.

txtMsgFrom.setText(Html.fromHtml(convertToHtml(txtMsgFrom.getText().toString()) + "         ")); // 10 spaces

Its easier with Unicode from here.
So with this you can archive the Unicode format
new TextView("Hello\u00A0world");
better than HTML string.

simplified gravity + layout_gravity usage
left + right layout files

private static final int WIDH_HOUR = 382;
#Override

setContentView(R.layout.activity_main);

mText = (TextView) findViewById(R.id.activity_main_text);
relativeLayout = (RelativeLayout) findViewById(R.id.activity_main_relative);
mText.setText("aaaaa dfsafsa afdsfa fdsafas adfas fdasf adfsa dsa aaaa dfsafsa afdsfa fdsafas adfas fdasf adfsa");
ViewTreeObserver vto = mText.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
if (mFirstTime) {
Layout layout = mText.getLayout();
int lines = layout.getLineCount();
int offset = layout.layout.getLineWidth(lines - 1);
int freeSpace = width - offset;
TextView hour = new TextView(MainActivity.this);
hour.setText("12:20");
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
if (freeSpace > WIDH_HOUR) {
params.addRule(RelativeLayout.ALIGN_BOTTOM, R.id.activity_main_text);

}
}
});
}
public int getScreensWidh() {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
return size.x;
}
Two Public Methods
public abstract int getLineCount ()
Return the number of lines of text in this layout.
public int getLineWidth(int line)
Gets the unsigned horizontal extent of the specified line, including leading margin indent and trailing whitespace.

You can use the layout and code below to achieve the desired effect.
Source code gist
What I have used is get the width of the text + the time layout and check if this exceeds the container layout width, and adjust the height of the container accordingly. We have to extend from FrameLayout since this is the one which allows overlapping of two child views.
This is tested to be working on English locale. Suggestions and improvements are always welcome :)
Hope I've helped someone looking for the same solution.

I guess the easiest way to achieve this kind oflayout would be to add enough blank space in your message to be sure there is enough space on the right to not cover the time (I don't see any other easy way to have a margin/padding/positioning for the last line of your text only)
Then you just place the time in the relative as an align bottom right

I suggest other solution. If you know max bubble width and time width, then you can precalculate how to place your views.
Layout:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
tools:text="This is text"/>
<TextView
android:id="#+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="10sp"
tools:text="10:10"/>
</RelativeLayout>
Code:
fun setTextAndTime(textView: TextView, timeView: TextView, text: String, time: String) {
// screen width - offset from bubble
val maxWidth: Int = Resources.getSystem().displayMetrics.widthPixels - context.resources.getDimensionPixelSize(R.dimen.bubble_offset)
val timeWidth: Int = getTextWidth(time, 10f)
textView.text = text
timeView.text = time
textView.measure(makeMeasureSpec(maxWidth, EXACTLY), makeMeasureSpec(0, UNSPECIFIED))
val offset = textView.layout.getLineWidth(textView.layout.lineCount - 1)
val freeSpace = maxWidth - offset
val moveTimestampBelow = freeSpace < timeWidth
val multilineContent = textView.layout.lineCount > 1
val params = RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT)
when {
moveTimestampBelow -> params.apply {
addRule(RelativeLayout.BELOW, textView.id)
addRule(RelativeLayout.ALIGN_PARENT_RIGHT)
}
multilineContent -> params.apply {
params.addRule(RelativeLayout.ALIGN_BOTTOM, textView.id)
addRule(RelativeLayout.ALIGN_PARENT_RIGHT)
}
else -> params.apply {
params.addRule(RelativeLayout.ALIGN_BOTTOM, textView.id)
addRule(RelativeLayout.END_OF, textView.id)
}
}
timeView.layoutParams = params
}
private fun getTextWidth(text: String, textSizeSp: Float): Int {
val textPaint = Paint()
val pxSize = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, textSizeSp, context.resources.displayMetrics)
textPaint.textSize = pxSize
textPaint.style = Paint.Style.FILL
val result = Rect()
textPaint.getTextBounds(text, 0, text.length, result)
return result.width()
}

The previous answers didn't satisfy my needs as they were too complex and the scrolling on RecyclerView was way too slow! I could feel the stutter while scrolling. So, I modified #Rahul Shuklas answer to make it more efficient. I am sharing my result below. The code is self explanatory, I have added comments for more understandability.

doMeasure()
}
