I want to change the font weight in TextView but i can't find the required method.
How can i do it without creating a new font?
You can only show a TextView as Light, Regular and Condensed if the font that you're referencing allows those styles.
private TextView AB;
Typeface someFontName-condensed = Typeface.createFromAsset(getAssets(), "assets/NameOfFont-condensed.ttf");
AB = (TextView) findViewById(R.id.myTextViewId);
AB.setTypeface(someFontName-condensed);
I have found the right answer. There is the static method:
open static fun create(family: Typeface?, weight: Int, italic: Boolean): Typeface
For example, if you want the font weight to be 700:
var text = findViewById<TextView>(R.id.text)
text.typeface=Typeface.create(null,700,false)

in before xml in TextView we have
holder.binding.iconInfo.text = "&#x${iconValue}"
and set out icon font to it with typeface dose anyone can help same thing but with jetpack compose
The specific syntax you mention that can be used with TextViews is due to the fact that XML is used when defining layouts. That is an XML numeric character entity that specifies a character with its unicode value in hexadecimal notation.
So it is not related to TextViews, layouts, fonts or icons.
If you want to do the same with a String in Kotlin and the character value is dynamic, you can do something like this
val text = "${Char(iconValue)}"
In Compose a custom font can be defined either as part of your Theme -> Typography and then used as text style or you can define it directly like this
val fontFamily = FontFamily(
// If you have the font in resources
Font(R.font.my_font_normal, weight = FontWeight.Normal),
Font(R.font.my_font_bold, weight = FontWeight.Bold),
Font(R.font.my_font_italic, weight = FontWeight.Normal, style = FontStyle.Italic),
// If you are loading the font at runtime from a file
Font(File(...), weight = FontWeight.Normal),
// ...
)
// Use with Text composable
Text(text = text, fontFamily = fontFamily)
Trying to create a linear layout programmatically and setting its width and height by layout params. But it seems layout params isn't working.
this is the code:
// CREATING A NEW LINEAR LAYOUT PROGRAMMATICALLY
LinearLayout linearLayout = new LinearLayout(getActivity());
ViewGroup.LayoutParams layoutParams = new
ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
linearLayout.setLayoutParams(layoutParams);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
// CREATING CHILDDRENS (TEXT VIEWS)
TextView name = new TextView(getContext(), null, 0, R.style.item_layout_style);
name.setText("Pine");
TextView qty = new TextView(getContext(), null, 0, R.style.item_layout_style);
qty.setText("10");
TextView cost = new TextView(getContext(), null, 0, R.style.item_layout_style);
cost.setText("785");
TextView tCost = new TextView(getContext(), null, 0, R.style.item_layout_style);
tCost.setText("1000");
// SET TEXT VIEW TO LINEAR LAYOUT
linearLayout.addView(name);
linearLayout.addView(qty);
linearLayout.addView(cost);
linearLayout.addView(tCost);
// SET LINEAR LAYOUT TO PINE LAYOUT
LinearLayout daddy= (LinearLayout) view.findViewById(R.id.layout);
daddy.addView(linearLayout, 2);
// Return the view
return view;
I have root layout (daddy) which has many linear layouts (vertically oriented), but I need to create a linear layout programmatically and add that to "daddy". But the text views are sticked together, they aren't getting the entire space horizontally.
Do help me!
Everything is fine with the code. It is the style that I tried to give to text views, they weren't getting layout weight, width and height. How did I find this out? Well I set the linear layout's background-color to black to see if it's really not getting width and height set by LayoutParams. And I wasn't wrong! Width was set to match parent. So what I did was create a new layout param for text views and set it to them.
My ImageView is matching screen size on x-axis and is using remaining space on y-axis in my layout. I want to create bitmap into this ImageView with exactly the same size as the ImageView is. How to make it please? Can it be done by some automatic setting, should I call some measure function?
I tried SetAdjustViewBounds() but it didn't work for me.
Creating Bitmap big enough (I don't like much such a memory wasting) and setting SetScaleType(ImageView.ScaleType.Matrix) works, but still when I'm making drawing operations on canvas, I don't know real size of area I should paint into, both canvas and bitmap height are equal to yScreen while imgWeekView height is pretending to be 0, even though it paints whole desired area with gray color.
imgWeekView = new ImageView(context);
//imgWeekView.SetAdjustViewBounds(true);
imgWeekView.SetScaleType(ImageView.ScaleType.Matrix);
layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MatchParent, LinearLayout.LayoutParams.WrapContent,1f);
layoutParams.Height = 0;
imgWeekView.LayoutParameters = layoutParams;
Bitmap bitmap = Bitmap.CreateBitmap((int)xScreen, (int)yScreen, Bitmap.Config.Argb8888);
cnvWeekView = new Canvas(bitmap);
imgWeekView.SetImageBitmap(bitmap);
linearLayout.AddView(imgWeekView); //whole activity layout
//Test
cnvWeekView.DrawColor(new Color(128, 128, 128));
Paint paint = new Paint(PaintFlags.AntiAlias);
paint.Color = new Color(255, 255,0);
cnvWeekView.DrawCircle(50, 50, 40, paint);
Finally I found a way how to measure my ImageView and here I will post my answer.
I believed that there should be much easier solution, but maybe there isn't. From this question I took most of the important data:
How to get the width and height of an android.widget.ImageView?
Things look however a little different in my android application and I'm not experienced enough to tell why. I had to change things a little. I had to learn a bit about interfaces and this question helped too.
Implementing the View.IOnTouchListener interface
Here is how I combined things. First I created class that will do the measure.
public class MyPredrawListener : Java.Lang.Object, ViewTreeObserver.IOnPreDrawListener
{
ImageView imageView;
public MyPredrawListener(ImageView img)
{
imageView = img;
}
public bool OnPreDraw()
{
imageView.ViewTreeObserver.RemoveOnPreDrawListener(this);
int finalHeight = imageView.MeasuredHeight;
int finalWidth = imageView.MeasuredWidth;
Bitmap bitmap = Bitmap.CreateBitmap(finalWidth, finalHeight, Bitmap.Config.Argb8888);
imageView.SetImageBitmap(bitmap);
//Test to see result
Canvas cnv = new Canvas(bitmap);
Paint paint = new Paint();
paint.Color = new Color(255, 255, 0);
cnv.DrawColor(new Color(128, 128, 128));
cnv.DrawCircle(finalWidth-50, finalHeight-50, 50, paint);
return true;
}
}
And in code where I create my imageView I set the listener like this.
imgWeekView = new ImageView(context);
MyPredrawListener listener=new MyPredrawListener(imgWeekView);
imgWeekView.ViewTreeObserver.AddOnPreDrawListener(listener);
In OnPreDraw function I put test code to see the result graphically, clearing bitmap to gray color and painting yellow circle to bottom right of a view.
I am programmatically creating a text view and trying to place another textView right next to the first one. But I am unable to do it.
Here is the code I have written,
//1st textview
TextView itemText = new TextView(context);
itemText.setText(mItemText);
Typeface itemFont = Typeface.createFromAsset(context.getAssets(), "fonts/" + "Roboto" + ".ttf");
itemText.setTypeface(itemFont,Typeface.BOLD);
itemText.setPadding(0, padding, 0, 0);
itemText.setId(10);
RelativeLayout.LayoutParams itemTextParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.MATCH_PARENT);
itemTextParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
itemTextParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
itemText.setTextSize(font_size);
itemText.setLayoutParams(itemTextParams);
//2nd text view
TextView seperator = new TextView(context);
seperator.setText(mSeperator);
seperator.setPadding(0,padding,0,0);
seperator.setTypeface(null,Typeface.BOLD);
RelativeLayout.LayoutParams seperatorParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
seperatorParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
seperatorParams.addRule(RelativeLayout.RIGHT_OF,itemText.getId());
seperatorParams.addRule(RelativeLayout.CENTER_VERTICAL);
seperator.setLayoutParams(seperatorParams);
seperatorParams.addRule(RelativeLayout.CENTER_HORIZONTAL) works, but when I use seperatorParams.addRule(RelativeLayout.RIGHT_OF,itemText.getId()) , the text is not shown.
Can anyone point out where I am going wrong? Or is there any other way to do this?
The width of itemTextParams is set to MATCH_PARENT, so there's no space to put anything to the right of it. Change it to WRAP_CONTENT or define a width value.
I'm trying to align right text in my dialog.
How can I do that ?
I've tried to:
TextView loadMsg = new TextView(context);
loadMsg.setText("טוען...");
loadMsg.setGravity(Gravity.RIGHT);
dialog.setView(loadMsg);
dialog.show();
But the text does not show.
Sub-way: Create a sub layout and set content view by this
dialog.setContentView(R.layout.dialog_layout);
And design the sub layout the way you like :D
This is because you set the gravity inside the TextView. But if your TextView is laid out with WRAP_CONTENT the gravity really doesn't matter for such a short String. You should insert the TextView inside some Layout, specify FILL_PARENT and setting the layout as the Dialog content view
// width is FILL_PARENT -1, height is WRAP_CONTENT -2
ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(-1, -2);
LinerLayout layout = new LinearLayout(context, params);
layout.addView(loadMsg, params);
dialog.setView(layout);
Alternatively, you can set the gravity on the layout itself and set the TextView's width to WRAP_CONTENT
Maybe you are missing LayoutParams in which you have to define heigh and width. If you use wrap_content for width then it would not be aligned as there will no be any extra space.
