    seekbar_pay_restaurant_.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
                @Override
                public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                    //change position of seekebar tool tip according to seekbar progress               
                    int x = seekBar.getThumb().getBounds().left;
                    Log.v("y value ",""+x);
                    int width = seekBar.getThumb().getMinimumWidth();
                    int textWidth=tv_tool_type_food_.getMeasuredWidth();
                    Log.v("textview Width","width"+textWidth);
                    Log.v("width",""+ width);
                    tv_tool_type_food_.setX(x);
                    if (seekbar_pay_restaurant_.getProgress() == 0) {
                        tv_tool_type_food_.setText(getResources().getString(R.string.hint_fast_food__));
                        // tv_tool_type_food_.setX(y);
                        return ;
                    } else if (progress == 1) {
                        tv_tool_type_food_.setX(x);
                        tv_tool_type_food_.setText(getResources().getString(R.string.hint_fast_casual__));

// Seek bar code          
    seekbar_pay_restaurant_.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { 
                @Override 
                public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                    //change position of seekebar tool tip according to seekbar progress                
                    int x = seekBar.getThumb().getBounds().left;
                    Log.v("y value ",""+x);
                    int width = seekBar.getThumb().getMinimumWidth();
                    int textWidth=tv_tool_type_food_.getMeasuredWidth();
                    Log.v("textview Width","width"+textWidth);
                    Log.v("width",""+ width);
                    if(x < max_x ) { // This will prevent the movement of text view out side
                       tv_tool_type_food_.setX(x);
                    }
                    if (seekbar_pay_restaurant_.getProgress() == 0) { 
                        tv_tool_type_food_.setText(getResources().getString(R.string.hint_fast_food__));
                        // tv_tool_type_food_.setX(y); 
                        return ; 
                    } else if (progress == 1) {
                        tv_tool_type_food_.setX(x);
                        tv_tool_type_food_.setText(getResources().getString(R.string.hint_fast_casual__));
                        return ; 
                    } else if (progress == 2) {
                      // tv_tool_type_food_.setX(x ); 
                        tv_tool_type_food_.setText(getResources().getString(R.string.hint_casual__));
                        return; 
                    } else if (progress == 3) {
                          tv_tool_type_food_.setText(getResources().getString(R.string.hint_fine_dyning__));
                        return; 
                    } 
                    tv_tool_type_food_.setText(getResources().getString(R.string.hint_fast_food__));
                } 
                @Override 
                public void onStartTrackingTouch(SeekBar seekBar) {
                } 

                @Override 
                public void onStopTrackingTouch(SeekBar seekBar) {
                } 
            }); 

Best way to calculate that value is

int seek_bar_width = seekbar.getMeasuredWidth();
int text_view_with = textview.getMeasuredWidth();
int max_x = seekbar.getX()+seek_bar_width-text_view_with;

Hope this helps!

Answer 2

If you want to move the text view with the seekbar position, then you will need to add this:

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();
int height = display.getHeight();

if (textview.getX() > width-textview.getLayoutParams().width) {
   textview.setX(width-textview.getLayoutParams().width);
}

This "if" will prevent doing that problem.
