andriod 动态创建控件

 Button btNext=(Button)findViewById(R.id.next);
        btNext.setOnClickListener(new Button.OnClickListener(){
            public void onClick(View view){
               //创建一个布局管理器控件
                LinearLayout linearLayout=new LinearLayout(MainActivity.this);
                setContentView(linearLayout);
                //设置orientation为horizontal,1表示为vertical
                linearLayout.setOrientation(0);
                TextView tvSecond=new TextView(MainActivity.this);
                tvSecond.setText("这是Android奉献给你的第二个页面");
                Button btNext2=new Button(MainActivity.this);
                btNext2.setText("下一步");
                btNext2.setId(2);
                LinearLayout.LayoutParams lp1 = new LinearLayout.LayoutParams(
                        ViewGroup.LayoutParams.WRAP_CONTENT,
                        ViewGroup.LayoutParams.WRAP_CONTENT);
                linearLayout.addView(tvSecond,lp1);
                linearLayout.addView(btNext2,lp1);
                btNext2.setOnClickListener(new View.OnClickListener(){
                    public void onClick(View view){
                         //这次只放置一个TextView不需要布局管理器
                        TextView tv3=new TextView(MainActivity.this);
                        tv3.setText("恭喜你已来到最后一个页面！");
                        //直接让页面显示一个TextView
                        setContentView(tv3);
                    }
                });
            }
        });

类似
     Button btNext=(Button)findViewById(R.id.next);
        btNext.setOnClickListener(new ButtonCreateClickListener());

    }
    private class  ButtonCreateClickListener implements View.OnClickListener {
        public void onClick(View view) {
            //创建一个布局管理器控件
            LinearLayout linearLayout = new LinearLayout(MainActivity.this);
            setContentView(linearLayout);
            //设置orientation为horizontal,1表示为vertical
            linearLayout.setOrientation(0);
            TextView tvSecond = new TextView(MainActivity.this);
            tvSecond.setText("这是Android奉献给你的第二个页面");
            Button btNext2 = new Button(MainActivity.this);
            btNext2.setText("下一步");
            btNext2.setId(2);
            LinearLayout.LayoutParams lp1 = new LinearLayout.LayoutParams(
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            linearLayout.addView(tvSecond, lp1);
            linearLayout.addView(btNext2, lp1);
            btNext2.setOnClickListener(new btNext2ClickListener());
        }
    }

    private class btNext2ClickListener implements View.OnClickListener {

        public void onClick(View v) {
            //这次只放置一个TextView不需要布局管理器
            TextView tv3 = new TextView(MainActivity.this);
            tv3.setText("恭喜你已来到最后一个页面！");
            //直接让页面显示一个TextView
            setContentView(tv3);

        }
    }

 创建按钮

  Button btNext=(Button)findViewById(R.id.next);
        btNext.setOnClickListener(new ButtonCreateClickListener());

    }
    private class  ButtonCreateClickListener implements View.OnClickListener {
        public void onClick(View view) {

            //创建一个button按钮
            Button btn1 = new Button( MainActivity.this);
            btn1.setText("this is a button");
            btn1.setId(1);
            TableLayout pTableLayout=(TableLayout)findViewById(R.id.table2);
            pTableLayout.addView(btn1);

        }
    }

 可以是

private class  ButtonCreateClickListener implements View.OnClickListener {
        public void onClick(View view) {

            //创建一个button按钮
            Button btn1 = new Button( MainActivity.this);
            btn1.setText("this is a button");
            btn1.setId(1);
            TableRow pTableRow=(TableRow)findViewById(R.id.TableRow2);
            pTableRow.addView(btn1);

        }
    }
