try this its working fine

this.row = (LinearLayout)findViewById(R.id.tags); this.row.setOrientation(LinearLayout.VERTICAL); LinearLayout one = new LinearLayout(this);

    //get the size of the screen
    Display display = getWindowManager().getDefaultDisplay();
    this.screenWidth = display.getWidth();  // deprecated
    this.screenHeight = display.getHeight();// depreceted

    for(int i=0; i<6; i++) {

        one.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));

        this.button = new Button(this);
        button.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        if(i==0) {
            this.button.setText("Muhammad Aamir");
        } else if(i==1) {
            this.button.setText("Ahsan");
        } else if(i==2) {
            this.button.setText("Mujahid");
        } else if(i==3) {
            this.button.setText("Waqas");
        } else if(i==4) {
            this.button.setText("Ali");
        } else {
            this.button.setText("Ahmer");
        }

        //get the size of the button text
        Paint mPaint = new Paint();
        mPaint.setAntiAlias(true);
        mPaint.setTextSize(button.getTextSize());
        mPaint.setTypeface(Typeface.create(Typeface.SERIF, Typeface.NORMAL));
        float size = mPaint.measureText(button.getText().toString(), 0, button.getText().toString().length());
        size = size+14;
        this.totalTextWidth += size;

        if(totalTextWidth < screenWidth) {
            one.addView(button);
        } else {
            this.row.addView(one);
            one = new LinearLayout(this);
            one.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
            one.addView(button);
            this.totalTextWidth = size;
        }
    }
    this.row.addView(one);
}
