Answer 1

It may be helpful. I did something like that, and in my solution I am scaling down textView, but you can set shorter text.

    if(textView.getWidth() > 0) {
        float widthOfTheText = textView.getPaint().measureText(textView.getText());
        if(widthOfTheText > textView.getWidth()) {
            //exceeds, let scale it
            textView.setTextScaleX((textView.getWidth()-0.1f)/widthOfTheText);
        } else {
            //not exceeds
        }
    } else {
        //not layouted yet
        textView.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
            @Override
            public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
              TextView tv = (TextView) v;
              float widthOfTheText = tv.getPaint().measureText(tv.getText());
              tv.setTextScaleX((tv.getWidth()-0.1f)/widthOfTheText);
              tv.removeOnLayoutChangeListener(this);

              if(widthOfTheText > tv.getWidth()) {
                 //exceeds, let scale it
                 tv.setTextScaleX((textView.getWidth()-0.1f)/widthOfTheText);
              } else {
                 //not exceeds
              }
           }
       });
    }
