How to make all the TextView childs to changed the color of text?

I have a LinearLayout, mRoot, and it has two child of TextView, such as
private TextView mNameView;
private TextView mValueView;
and I also set these TextView with ColorStateList. Now, the question is when I press the mRoot, those TextView can't change the color of text.
But when I make the mRoot as the item of ListView, then when I press the item, it can change the color of text.
Can anyone help me with this?

Try setting the android:duplicateParentState attribute to true in your TextView declarations in XML.

How can I set the text of the TextView within a LinearLayout?

I have created a custom LinearLayout through program which have a custom TextView within it. I have not added the TextView using inflater. Now I want to use this LinearLayout multiple times in XMl layout. But the problem is that how can I set the text of these TextView within the LinearLayout?
Any ideas??

If I right understand it will help you. Good luck!
LinearLayout layout = findViewById(id_linear_layout);
((TextView) layout.findViewById(id_textview)).setText("Text");

When adding the customTextView set the tag using setTag method. And then to retrieve it use linearLayout.findViewWithTag method to retrieve the customTextView and as usual use setText to set the text
You an also alternatively set the id using setId and retrieve it using findViewById method

Use a reference of that TextView to to set the text.
Then add this TextView to LinearLayout.
ex -
TextView text = new TextView(yourActivity.this);
text.setText("Sample Text");
ll.addView(text);
// ll is your LinearLayout.

how to remove space if we hide edittext in android?

i am doing like these in my xml i using spinner.In spinner if i select other edittext should be visible.before that edittext space must be remove.
eidttext.setVisibility(android.view.View.INVISIBLE);
eidttext.setVisibility(android.view.View.GONE);
i want to remove space of the edittext when it is inVisible.if any have idea.

You use View.GONE to free the space for other widgets, View.INVISIBLE will keep the space, but make the widget, well, invisible. View's documentation

Try to use
View edittext;
Instead of Button edittext;
edittext.setVisibility(View.GONE);
This will help you

In XML use to hide a element with their shape height or width:
android:visibility="gone"

How to properly align form?

I have a form with a format of:
<LinearLayout>
<RelativeLayout>TextView EditText Button</RelativeLayout>
<RelativeLayout>TextView EditText Button</RelativeLayout>
<RelativeLayout>TextView EditText Button</RelativeLayout>
<RelativeLayout>TextView EditText Button</RelativeLayout>
</LinearLayout>
I have aligned the TextView to parentLeft, the Button to parentRight. And so far, the EditText to toLeftOf Button. Now, I want the EditText to all line up with the longest TextView, however I can't seem to use toRightOf of a TextView from a different layout. I'm not even sure that's the best way to do it.
What is the proper way to get everything to line up straight?

Consider using TableLayout instead

You can try replacing the LinearLayout with RelativeLayoutand and remove the RelativeLayout for each row or use TableLayout as asahi suggested.
