How can I change the font in radio buttons that I am creating from a string array?

My app creates different answers (radio buttons) to select based on what I have in arrays, but I can't figure out how to change the font of these answers. Usually I would just change the font in the layout.xml file, but I only have the radio group there, not the actual buttons.
Here is my code:
private void createRadioButton(View view) {
RadioGroup group = (RadioGroup)view.findViewById(R.id.radioGroup);
String[] answers = getResources().getStringArray(R.array.question_1_answers);
for (int i=0;i<answers.length;i++){
String answer = answers[i];
RadioButton button = new RadioButton(getActivity());
button.setText(answer);
group.addView(button);
}
}
I wanted to do something like this:
Typeface typeface = getResources().getFont(R.font.myfont);
button.setTypeface(typeface);
but that requires API 26 and I'm working with API 16

Try this :
RadioButton rb = (RadioButton) findViewById(R.id.radiobutton);
Typeface font = Typeface.createFromAsset(getAssets(), "MyFont.ttf");
rb.setTypeface(font);

Just create a CustomRaioButton and add it to your view:
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Typeface;
import android.util.AttributeSet;
public class CustomRadioButton extends android.support.v7.widget.AppCompatRadioButton {
public CustomRadioButton(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init(context);
}
public CustomRadioButton(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);
}
public CustomRadioButton(Context context) {
super(context);
init(context);
}
private void init(Context context) {
Typeface typeface = getResources().getFont(R.font.myfont);
setTypeface(typeface);
a.recycle();
}
}

How to set your shape for default background for TextView?

I need to set my shape as default background for all of my texts and I don't know how to do this, I want to add many TextView to my project so it's really important for me to do this, I've tried searching the internet but no luck :(

try this code
import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;
public class CustomTextView extends TextView{
public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public CustomTextView(Context context) {
super(context);
init();
}
public void init() {
if(!isInEditMode()){
setBackgroundResource("Your shape file id ");// like r.drawable.shape_textview
}
}
}

Is there any way to programatically select text in a TextView?

I have a TextView that I'm looking to allow the user to search in for a specific string. If the string is found, it should highlight. Using a background span is too slow and awkward, so I am trying to figure out if I can just have it select the string. I know with EditText this would be possible using setSelection(), but I don't want the user to be able to edit the text, while still being able to manually highlight text, which I can't seem to do manage with an EditText.
I guess, then it's an either or; is it either possible to programmatically select text in a TextView or possible to allow text selection without allowing editing in an EditText?
Note: I'm actually using a custom view extending TextView, so I'm assuming it's either that or extend EditText; I'm just not sure which (if either) will work.

Not sure whether the question is still actual, I will provide my solution. Maybe will be useful for people coming from search engines.
So the purpose, as I understood, is to select all text in TextView without being able to modify its content. I didn't check how effective it is against very large text, but hope that not so bad.

SlidingPaneLayout: slide without smooth animation?

I'm using the new SlidingPaneLayout available in the latest support library, which provides the openPane() and closePane() methods to smooth open and close the panel. Unfortunately, there are no public methods to do so without animation.
Is there a way to still do this? I have a feeling reflection may be necessary.
P.S. The file is available under sdk/extras/android/support/v4/src/java/android/support/v4/widget/.

I ended up writing a subclass that provides two methods, openPaneNoAnimation() and closePaneNoAnimation(). Yes, it's reflection, and may stop working with future support libraries, but for now it does the job. Worst case, the methods fall back to using openPane() and closePane().

Error in setting custom font - Android

For an Android widget I've been developing, I'm trying to use a custom font. I've looked up some tutorials on the internet, and I found several ways to do it. I chose one and tried to implement it, but I get an error and I can't figure out why. The technique uses a seperate class (of which I've posted the code below), to set the font. In this code I get an error at the customFont line in setCustomFont. It says that customFont cannot be resolved to a variable. Can anybody help me out as to why this is happening?
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.TextView;
public class TypefacedTextView extends TextView {
private static final String TAG = "TextView";
public TypefacedTextView(Context context) {
super(context);
}
public TypefacedTextView(Context context, AttributeSet attrs) {
super(context, attrs);
setCustomFont(context, attrs);
}
public TypefacedTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setCustomFont(context, attrs);
}
private void setCustomFont(Context ctx, AttributeSet attrs) {
TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.TypefacedTextView);
String customFontl = a.getString(R.styleable.TypefacedTextView_typeface);
setCustomFont(ctx, customFont); // get an error here
a.recycle();
}
public boolean setCustomFont(Context ctx, String asset) {
Typeface tf = null;
try {
tf = Typeface.createFromAsset(ctx.getAssets(), asset);
} catch (Exception e) {
Log.e(TAG, "Could not get typeface: " + e.getMessage());
return false;
}
setTypeface(tf);
return true;
}
}

String customFontl = a.getString(R.styleable.TypefacedTextView_typeface);
setCustomFont(ctx, customFont); // get an error here
Your variable is declared as customFontl (note final l), and you are trying to use it as customFont. I would guess the error is that customFont is not defined or something alike, as it is the case.

i have try this may it help you in this code my font is in asset/fonts folder
if it is only in asseet than replace in code fonts/
public class MyTextView extends TextView{
public MyTextView(Context context, AttributeSet attrs, int defStyle) {
