i created simple widget as custom checkBox as this below code, in this code setting custom font work fine but i can't check or uncheck CheckBox
public class CustomFontCheckBox extends AppCompatCheckBox {
public CustomFontCheckBox(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setTypeface(FontManager.getInstance(getContext()).loadFont("fonts/my_font.ttf"));
}
public CustomFontCheckBox(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
#SuppressWarnings("unused")
private void internalInit(Context context, AttributeSet attrs) {
}
}
xml layout:
<com.myapp.test.Widgets.CustomFontCheckBox
android:id="#+id/ch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="#dimen/sickness_depth_marginRight"
android:button="#null"
android:buttonTint="#color/colorAccent"
android:drawableRight="?android:attr/listChoiceIndicatorMultiple"
android:text="#string/diabetes"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#color/body_text_color"/>
Well I think you are messing with its constructor and its style use it like this
public class CustomFontCheckBox extends AppCompatCheckBox {
public CustomFontCheckBox(Context context) {
super(context);
init();
}
public CustomFontCheckBox(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public CustomFontCheckBox(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}
private void init(){
//set your typeface here.
// setTypeface("");
}
}

Following is my custom TextView Class:
public class MontTextView extends android.support.v7.widget.AppCompatTextView{
public MontTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public MontTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MontTextView(Context context) {
super(context);
init();
}
public void init() {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/Montserrat-Regular.ttf");
setTypeface(tf ,1);
}
}
And in XML I use it like this:
<com.minimalist.gorakh.customviews.MontTextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="#dimen/_20sdp"
android:text="Text"
android:textColor="#fff"
android:textSize="#dimen/_25ssp"
app:layout_constraintBottom_toBottomOf="#+id/betaView"
app:layout_constraintStart_toStartOf="#+id/betaView"
app:layout_constraintTop_toTopOf="#+id/betaView" />
This is working in pre-lollipop(v-19) like this:
And on a marshmallow emulator:
I copied the custom TextView code from a previous project, but couldn't get what am I doing wrong here.
Try this :
import android.widget.*;
import android.util.*;
import android.content.*;
import android.graphics.*;
public class MontTextView extends TextView{
public MontTextView (Context context) {
super(context);
init();
}
public MontTextView (Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MontTextView (Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}
private void init() {
setTypeface(Typeface.createFromAsset(getContext().getAssets(), "fonts/Montserrat-Regular.ttf"));
}
}
I am using custom Edittext like this
public class DosisEdittextFont extends TextView {
public DosisEdittextFont(Context context) {
super(context);
init(context);
}
public DosisEdittextFont(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);
}
public DosisEdittextFont(Context context, AttributeSet attrs,
int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(context);
}
private void init(Context context) {
Typeface t = Typeface.createFromAsset(context.getAssets(),
"fonts/Dosis-Regular.otf");
this.setTypeface(t);
}
}
But because of that cursor is not showing in EditText. how to set cursor in custom EditText?
You may extends EditText instead of TextView
Try This
public class CustomEditText extends EditText {
public CustomEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
if(!isInEditMode())
init(attrs);
}
public CustomEditText(Context context, AttributeSet attrs) {
super(context, attrs);
if(!isInEditMode())
init(attrs);
}
public CustomEditText(Context context) {
super(context);
if(!isInEditMode())
init(null);
}
private void init(AttributeSet attrs)
{
if (attrs!=null)
{
TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.CustomTextView);
String fontName = a.getString(R.styleable.CustomTextView_fontFamily);
if (fontName!=null)
{
Typeface myTypeface = Typeface.createFromAsset(getContext().getAssets(), "fonts/"+fontName);
setTypeface(myTypeface);
}
a.recycle();
}
}
}
To Use In Your Layout
<CustomEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/etEmailId"
android:hint="#string/email"
android:textColor="#color/input_text_color"
android:textColorHint="#color/input_text_color"
customfont:fontFamily="YOUR FONT NAME.ttf"
/>
Reason for not appearance of cursor in edittext are many like your theme appearance
i.e. theme style or edittext background and one is that you extending TextView,
so try extending EditText in place of TextView as:
import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.EditText;
public class CustomEditText extends EditText {
private Context context;
private AttributeSet attrs;
private int defStyle;
public CustomEditText(Context context) {
super(context);
this.context = context;
init();
}
public CustomEditText(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
this.attrs = attrs;
init();
}
public CustomEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
this.context = context;
this.attrs = attrs;
this.defStyle = defStyle;
init();
}
private void init() {
Typeface font = Typeface.createFromAsset(getContext().getAssets(), "fonts/montserrat_bold.ttf");
this.setTypeface(font);
}
#Override
public void setTypeface(Typeface tf, int style) {
tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/montserrat_bold.ttf");
super.setTypeface(tf, style);
}
#Override
public void setTypeface(Typeface tf) {
tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/montserrat_bold.ttf");
super.setTypeface(tf);
}
}
and in you layout xml
<com.example.CustomEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/edittext"
android:hint="text"
android:textColor="#000000"
android:textColorHint="#000000"/>
So, try replacing textview with edittext , if still not resolve, this
occurs due to your activity theme or your edittext background
textView.setText is not working properly in a compound view.
Means Both hello and jack are appearing...
and jack is displayed below layout not appearing if I put some background color,...
Could somebody help... Thanks and regards...
Here is my code...
Layout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/chatLayout"
android:layout_width="300dp"
android:layout_height="400dp"
>
<TextView
android:id="#+id/chatNamed"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="Hello"
android:textColor="#ffffff"
android:textSize="20dp"
android:textStyle="bold"
android:layout_marginTop="10dp"
android:layout_marginLeft="10dp"
/>
</RelativeLayout>
CompoundView.java
public class ChatCompoundView extends RelativeLayout {
private static TextView zoneName;
public ChatCompoundView(Context context) {
this(context, null);
setView();
}
public ChatCompoundView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
setView();
}
public ChatCompoundView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setView();
}
public void setView()
{
inflate(getContext(), R.layout.chat_layout, this);
zoneName = (TextView) findViewById(R.id.chatNamed);
}
zoneName.setText("jack");
}
try this..
LayoutInflater mInflater;
public ChatCompoundView (Context context) {
super(context);
mInflater = LayoutInflater.from(context);
setView();
}
setView():
public void setView(){
mInflater.inflate(R.layout.custom_view, this, true);
TextView zoneName = (TextView) findViewById(R.id.chatNamed);
zoneName .setText("jack");
}
Yeah Now I got the Answer... Actually my constructors are called with this(context),.. and I need to call super(context)...
Code Changed to
public ChatCompoundView(Context context) {
super(context);
setView();
}
public ChatCompoundView(Context context, AttributeSet attrs) {
super(context, attrs);
setView();
}
public ChatCompoundView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setView();
}
Using the following code:
public class CustomView extends RelativeLayout {
public CustomView(Context context) {
this(context, null, 0);
}
public CustomView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public CustomView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initView();
}
private void initView() {
inflate(getContext(), R.layout.custom_view, this);
}
}
The layout is simple:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/custom_view_id"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#f00"/>
The hierarchyviewer shows the following:
The CustomView hierarchy is useless and I would like to remove it.
Is there a way to create a custom view extending a ViewGroup without adding that additional View?
If your CustomView is already a RelativeLayout in you XML layout you can just delete the RelativeLayout with "#+id/custom_view_id" and use as father the tag
That will merge the children with the CustomView without using an extra RelativeLayout.
The CustomView will setBackgroundColor
public class CustomView extends RelativeLayout {
public CustomView(Context context) {
this(context, null, 0);
}
public CustomView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public CustomView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initView();
}
private void initView() {
setBackgroundColor(Color.parseColor("#f00"));
inflate(getContext(), R.layout.custom_view, this);
}}
and the layout xml file will be:
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<!-- children here -->
</merge>
I'm trying something like this
public class CustomViewSubclass extends HorizontalScrollView{
private LinearLayout layout;
public CustomViewSubclass(Context context) {
this(context,null,0);
}
public CustomViewSubclass(Context context, AttributeSet attrs) {
this(context,attr,0);
}
public CustomViewSubclass(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
layout = new LinearLayout(context);
}
// This is called from the `Activity`
public void startAsyncTask() { // code }
// This method is called in the `onPostExecute()` of an `AsyncTask` subclass
public void doSomething(Context context) {
ImageView image = ImageView(context);
layout.addView(image); // NullPointerException here, layout seems to be null
}
but it seems that layout on doSomething() is null. How is that even possible? I'm initializing it on the constructor... and I never re-initialize it again;
I'm adding my custom view via XML
<com.mypackage.CustomViewSubclass
android:layout_width="wrap_content"
android:layout_width="match_parent" />
Ok I fixed it, it was an stupid mistake made by me:
I used super() on the 3 methods, instead of using this().
public CustomViewSubclass(Context context) {
super(context,null,0);
}
public CustomViewSubclass(Context context, AttributeSet attrs) {
super(context,attr,0);
}
public CustomViewSubclass(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
layout = new LinearLayout(context);
}
Solution:
public CustomViewSubclass(Context context) {
this(context,null,0);
}
public CustomViewSubclass(Context context, AttributeSet attrs) {
this(context,attr,0);
}
public CustomViewSubclass(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
layout = new LinearLayout(context);
}
