Question

我试图以相对布局动态创建文本视图。

问题：如果屏幕上有足够的空间，如果没有足够的空间，如何将它们添加到RIGHT_OF。

    void addTravelActivities()
    {
        RelativeLayout travel_act_layout=(RelativeLayout) findViewById(R.id.rl_for_travelact);

        for (int i=0;i<=15;i++)
        {
            TextView tv=new TextView(this);
            tv.setId(i);
            tv.setText(traveliconName.get(i));
            tv.setBackgroundResource(R.drawable.round_rect_shape);
            tv.setCompoundDrawablesWithIntrinsicBounds(R.drawable.plus_profile,0, 0, 0);
            tv.setCompoundDrawablePadding(10);
            tv.setTextSize(16f);
            tv.setTextColor(this.getResources().getColor(R.color.tripoto_orange));
            tv.measure(0, 0);

    //              tv.setBackground(this.getResources().getDrawable(R.drawable.round_rect_shape,null));
            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
            if(i==0)
            {
                params.addRule(RelativeLayout.ALIGN_PARENT_TOP);
                params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
                params.setMargins(8,0, 8, 8);
                travel_act_layout.addView(tv,params);
                /*tv.addOnLayoutChangeListener(new OnLayoutChangeListener() {

                    @Override
                    public void onLayoutChange(View v, int left, int top, int right,
                            int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
                        // TODO Auto-generated method stub
                    int width=right-left;
                    Toast.makeText(NewProfileSettings.this,width+"", Toast.LENGTH_SHORT).show();
                    }
                });*/
            }
            else if(getWindowSize(tv.getMeasuredWidth())==true) {
            params.addRule(RelativeLayout.RIGHT_OF,i-1);
            params.setMargins(8,0, 8, 8);
            sum += tv.getMeasuredWidth();
            travel_act_layout.addView(tv,params);
    //              Toast.makeText(this, tv.getMeasuredWidth()+"",        Toast.LENGTH_SHORT).show();
            }
            else if(getWindowSize(tv.getMeasuredWidth())==false)
            {
                params.addRule(RelativeLayout.BELOW,i-1);
                params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
                params.setMargins(8,0,8,8);
                travel_act_layout.addView(tv,params);
            sum=0;
            }

        }

    }

    Boolean getWindowSize(int textViewWidth)
    {

        Display display = getWindowManager().getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        int width = size.x;
        int height = size.y;
        int layout_width=width-40-textViewWidth;
        if(layout_width>sum)
        return true;
        else
            return false;

    }

我可能接近这样做，因为我已经接受了这个

答案：

是Flow Layout是@Frank N. Stein建议的答案。但是你会发现很多库可以帮助你完成这项任务。如果你想避免使用库，这是我在研究时发现的最简单的方法：

只需要一个类和一些布局的更改，它就可以正常工作。

根据屏幕大小将Textviews添加到相对布局
