MainActivity

 show = (TextView)findViewById(R.id.getdirection);
         show1 = (TextView)findViewById(R.id.hide);
         rt = (RelativeLayout)findViewById(R.id.rl_ListView2);
show.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View v) {
                            // TODO Auto-generated method stub

                            if(rt.getVisibility()==View.INVISIBLE)
                            {
                                rt.setVisibility(View.VISIBLE);

                            }
                           show.setVisibility(View.INVISIBLE);


                        }
                    });
show1.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View v) {
                            // TODO Auto-generated method stub

                            if(rt.getVisibility()==View.VISIBLE)
                            {
                                rt.setVisibility(View.INVISIBLE);

                            }
                           show1.setVisibility(View.INVISIBLE);


                        }
                    });

推荐答案

尝试一下:

由于重量属性，您从一开始就在一半屏幕上获得layout1.您可以尝试在开始时不给重，并在单击按钮时以编程方式给重.

You are getting layout1 in half screen from starting due to weight property. You can try not giving weight in starting and give it programatically on button click.

button.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        button1.setVisibility(View.GONE);  //hide old button
        layout2.setVisibility(View.VISIBLE);  //show layout2
        //set Relativelayout 1 to half screen
        RelativaLayout.LayoutParams params = layout1.getLayoutParams(); 
        params.weight = 0.5;
        layout1.setLayoutParams(params);
    }
});
