Dynamic list not showing all elements in a linear layout

I have a horizontal linear layout that is filled with TextViews from a dynamic list, but it doesn't show all elements since it seems to be out of the parent's bounds. What I need is to fill the space below if needed.
Here's my code:
The xml:
<RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content">
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:id="#+id/imageView_serie" android:contentDescription="imatge_serie"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Nom_serie"
android:textSize="20dp"
android:layout_marginLeft="8dp"
android:id="#+id/nom_serie" android:contentDescription="nom_serie" tools:text="Nom_serie"
android:layout_toRightOf="#id/imageView_serie"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize = "16dp"
android:layout_marginLeft="8dp"
android:textStyle="bold"
android:id="#+id/any_serie" android:contentDescription="any_serie" tools:text="any_serie"
android:layout_toRightOf="#id/nom_serie"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Sinopsis"
android:textSize="12dp"
android:layout_marginLeft="8dp"
android:layout_marginTop = "8dp"
android:id="#+id/sinopsi_serie" android:contentDescription="sinopsis_serie" tools:text="sinopsis_serie"
android:layout_toRightOf="#id/imageView_serie"
android:layout_below = "#id/nom_serie"
/>
<RatingBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="26dp"
android:id="#+id/ratingbar_serie"
android:layout_below = "#id/imageView_serie"
android:layout_centerVertical="true"
style="?android:attr/ratingBarStyleSmall"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Puntuacio"
android:textSize="12dp"
android:layout_marginLeft="8dp"
android:layout_marginTop = "8dp"
android:id="#+id/puntuacio" android:contentDescription="puntuacio" tools:text="puntuacio"
android:layout_toRightOf="#id/ratingbar_serie"
android:layout_below = "#id/imageView_serie"
/>
</RelativeLayout>
<RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content">
<TextView
android:layout_width="65dp"
android:layout_height="wrap_content"
android:text="Casting:"
android:textSize="14dp"
android:layout_marginLeft="8dp"
android:layout_marginTop = "24dp"
android:id="#+id/casting" android:contentDescription="casting" tools:text="casting"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="10dp"
android:layout_marginLeft="8dp"
android:id="#+id/cast" android:contentDescription="cast" tools:text="cast"
android:layout_toRightOf="#id/casting"
/>
</RelativeLayout>
<RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content">
<TextView
android:layout_width="65dp"
android:layout_height="wrap_content"
android:text="Direccio:"
android:textSize="14dp"
android:layout_marginLeft="8dp"
android:layout_marginTop = "24dp"
android:id="#+id/direccio" android:contentDescription="direccio" tools:text="direccio"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="10dp"
android:layout_marginLeft="8dp"
android:id="#+id/dir" android:contentDescription="dir" tools:text="dir"
android:layout_toRightOf="#id/direccio"
/>
</RelativeLayout>
<RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Temporades:"
android:textSize="24dp"
android:textStyle="bold"
android:id="#+id/nTemporades" android:contentDescription="nTemporades" tools:text="nTemporades"
/>
</RelativeLayout>
<RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Comentaris"
android:textSize="24dp"
android:textStyle="bold"
android:id="#+id/titol_comentaris_serie" android:contentDescription="titol_comentari_serie" tools:text="titol_comentari_serie"
/>
</RelativeLayout>
<LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:id="#+id/panell"
android:orientation="horizontal">
</LinearLayout>
And this how I generate the text views from the list:
LinearLayout panell = (LinearLayout) findViewById(R.id.panell);
for (int i = 1; i <= 20; i++) {
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
TextView btn = new TextView(this);
btn.setId(i);
final int id_ = btn.getId();
btn.setText("button " + id_);
//btn.setBackgroundColor(Color.rgb(70, 80, 90));
panell.addView(btn, params);
btn = ((TextView) findViewById(id_));
btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Toast.makeText(view.getContext(),
"Button clicked index = " + id_, Toast.LENGTH_SHORT)
.show();
}
});
}
Here's my :
output

I recommend Google's flexbox-layout project: https://github.com/google/flexbox-layout
A FlexboxLayout (when configured correctly) has the ability to add any number of child TextViews in a line (like LinearLayout would), but will automatically "wrap" to the next line if a child wouldn't fit.

Why not try to use a ListView , if u add the same propreties every time

After apply above code
I am getting like this image
this image

We can do it easily as per attached image
Made visible when need of Highlighter under text views or adjacent of image.
or Made invisible when not need or pressed That's it .
Wrote code for same which is working .
text color change on the basis of text selection :
text_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#00b200"></item>
<item android:state_focused="true" android:color="#00b200"/>
<item android:state_selected="true" android:color="#000000"/>
<item android:color="#d3d3d3"></item>
</selector>

How to position an ImageView in the same place in different screen sizes?

I been working on a simple android app that calculates a person's Body Mass Index, I have all the features working but positioning the arrow in the right place in the color bar corresponding to the user's screen size is what Im stuck on. I have it working by setting the X and Y values of the arrow ImageView but obviously the place of the arrow changes when i test my application in different screen sizes even though im coverting a dp value to pixels. How can I position the arrow ImageView so that it stays the same in different screen sizes?

Add Linearlayout as subparent of childview,use its orientation and gravity attribute you can easily get the design in more optimize way and suitable for everyscreen size.
here i have used RelativeLayout as Parent and LinearLayout as sub-parent of childview.

TextView change to ImageView on same ButtonClick- uncompleted

I have a button. In onClick() it will show TextView and ImageView at the same time, with the same outcome.But I am facing a problem, the image doesn't load completely. Can anyone tell me why is it so? Thanks in advance!
Code for Button onClick
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
switch(count){
case 0 :
df = Typeface.createFromAsset(getAssets(),
"fonts/IDAutomationHC39M_FREE.otf");
ConvertToBitmap();
break;
case 1:
df = Typeface.createFromAsset(getAssets(),
"fonts/code128.ttf");
ConvertToBitmap();
break;
case 2:
df = Typeface.createFromAsset(getAssets(),
"fonts/Molot.otf");
ConvertToBitmap();
break;
case 3:
df = Typeface.createFromAsset(getAssets(),
"fonts/Days.otf");
ConvertToBitmap();
break;
case 4:
df = Typeface.createFromAsset(getAssets(),
"fonts/Paranoid.otf");
ConvertToBitmap();
break;
}
}
});
Code for TextView and ImageView
public void ConvertToBitmap(){
if (et.getText().toString().equals("")) {
//Clear textView
tv.setText("");
et.setText("");
tv.buildDrawingCache();
iv.setImageBitmap(tv.getDrawingCache());
}
else {
TextView tv1 = (TextView) findViewById(R.id.textView1);
tv1.setTypeface(df);
String editTextValue = et.getText().toString();
tv.setText(editTextValue);
tv.buildDrawingCache();
bmap = tv.getDrawingCache();
iv.setImageBitmap(bmap);
}
}
EDITED!

half or quarter black screen in android

I have an android activity that when I launch sometimes (about 1 in 4 times) it only draws quarter or half the screen before showing it. When I change the orientation or press a button the screen draws properly.
I'm just using TextViews, Buttons, Fonts - no drawing or anything like that.
All of my code for initialising is in the onCreate(). In this method I'm loading a text file, of about 40 lines long, and also getting a shared preference. Could this cause a delay so that it can't draw the intent?
Thanks in advance if anyone has seen anything similar.
EDIT - I tried commenting out the loading of the word list, but it didn't fix the problem.
EDIT 2 - I didn't manage to resolve the problem, but managed to improve it by adding a timer right at the end of the onCreate. I set a low refresh rate and in the tick changed the text of one of the controls. This then seemed to redraw the screen and get rid of the black portions of the screen.
Here is the activity
