大叔程序员的第九天 @动态添加Layout用Radio进行切换

压力一级级下传，越来越大

private View in;
private LinearLayout box;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
box = (LinearLayout)findViewById(R.id.box);
in = View.inflate(this, R.layout.inside, null); //添加子页面
box.addView(in);

}

动态添加一个子Layout至父Layout中去

再增加用RadioGroup进行切换，主要是View.inflate()方法及checkedId的判断，还有是Layout对象的removeAllView方法和addView方法

super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        box = (LinearLayout)findViewById(R.id.box);
        radio = (RadioGroup)findViewById(R.id.radioGroup1);
        btn0 = (RadioButton)findViewById(R.id.radio0);
        btn1 = (RadioButton)findViewById(R.id.radio1);
        btn2 = (RadioButton)findViewById(R.id.radio2);
        box.addView(View.inflate(MainActivity.this, R.layout.taobao,null)); //添加子页面
        radio.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                int i=0;
                if(btn0.getId()==checkedId){
                    i=0;
                }else if(btn1.getId()==checkedId){
                    i=1;
                }else if(btn1.getId()==checkedId){
                        i=2;
                }else{}
                switch(i){
                case 0:
                    box.removeAllViews();
                    box.addView(View.inflate(MainActivity.this, R.layout.taobao,null)); //添加子页面
                    break;
                case 1:
                    Log.v("xxx","yyy");
                    box.removeAllViews();
                    box.addView(View.inflate(MainActivity.this, R.layout.product, null)); //添加子页面
                    break;
                case 2:
                    box.removeAllViews();
                    box.addView(View.inflate(MainActivity.this, R.layout.service, null)); //添加子页面
                    break;
                }
                
            }
        });
        
        
    }
