Center of ScalableLayout

[lapngodoan]

Hi Ssomai, Thank for your library. I have a question. In the ScalableLayout, how can we put a view in the center of this layout? For example, in the scalable layout, I have 3 view: PreviousButton ---- TextView -----NextButton The content of textview is changed dynamically. How to ensure this text is alway the center of the layout? (Like RelaytiveLayout) Thank

Hello, thank you for your issue and interest in my work. Above, I beg your pardon for my english.

I suppose what you want that textview is in wrap content but dont move both buttons. is it right? I'll add another field for that feature, then I'll re-comment. If I am wrong, please re-comment to me.

Thank you for the issue.

Hello. I added the feature that I suppose. I added parameter 'pMoveSiblings' at method 'setTextView_WrapContent' of class 'ScalableLayout' and attached sample code what you want, I suppose. I hope these help.

LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
setContentView(ll);

mSL = new ScalableLayout(this, 2000, 500);
mSL.setBackgroundColor(Color.LTGRAY);
ScalableLayout.setLoggable();
ll.addView(mSL, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

Button btn_prev = new Button(this);
btn_prev.setText("Prev");
mSL.addView(btn_prev, 0, 0, 200, 500);

final TextView tv = new TextView(this);
tv.setText("TextView");
tv.setBackgroundColor(Color.RED);
mSL.addView(tv, 1000, 0, 1, 500);
mSL.setTextView_WrapContent(tv, TextView_WrapContent_Direction.Center_Horizontal, false, false);

Button btn_next = new Button(this);
btn_next.setText("Next");
mSL.addView(btn_next, 1800, 0, 200, 500);

Button btn_small = new Button(this);
btn_small.setText("Small");
btn_small.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        tv.setText(tv.getText().toString().substring(0, tv.getText().length()/2));
    }
});
ll.addView(btn_small, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

Button btn_large = new Button(this);
btn_large.setText("large");
btn_large.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        tv.setText(tv.getText()+"testtest");
    }
});
ll.addView(btn_large, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

Hi Youngmann Kim, This new update is what I really want.It helps me resolve my issues a lot. But I think, it'd better if we have TextView_WrapContent_Direction.Center_Vertical and TextView_WrapContent_Direction.Center (for both direction). How do you think about this? Anyway, thank for your great news!

[ssomai]

Yeah, you're right. I'll do it as soon as, then re-comment here.

Thanks. :)

Uhm...

TextView_WrapContent_Direction.Center_Vertical will be implemented easily.

But TextView_WrapContent_Direction.Center makes me confused.... Let me think about it.

Thanks :)

I'm sorry for late update.

I Implemented TextView_WrapContent_Direction.Center_Vertical. But I can't make TextView_WrapContent_Direction.Center, because I can't decide which direction is right to expand.

Thanks. :)
