Android组件ViewStub基本使⽤⽅法详解ViewStub可以在运⾏时动态的添加布局。帮助⽂档给定的定义是："A ViewStub is an invisible, zero-sized View that can be used to lazily inflate layout resources at runtime. When a ViewStubis made visible, or when inflate() is invoked, the layout resource is inflated. The ViewStub then replaces itself in its parentwith the inflated View or Views. Therefore, the ViewStub exists in the view hierarchy until setVisibility(int) or inflate() isinvoked. The inflated View is added to the ViewStub's parent with the ViewStub's layout parameters. Similarly, you candefine/override the inflate View's id by using the ViewStub's inflatedId property.”总之是：ViewStub可以给其他的view事先占据好位置，当需要的时候调⽤inflater()或者是setVisible（）⽅法显⽰这些View组件。:

: :package d_viewstub1;import ;import ssLint;import ty;import ;import ;import kListener;import ub;import ;public class MainActivity extends Activity { Button btn1, btn2; ViewStub viewStub; @Override protected void onCreate(Bundle savedInstanceState) { te(savedInstanceState); setContentView(ty_main); btn1 = (Button) ewById(n); btn2 = (Button) ewById(Btn); viewStub = (ViewStub) ewById(ub); lickListener(new OnClickListener() { @SuppressLint("NewApi") @Override public void onClick(View arg0) { ibility(E); } }); lickListener(new OnClickListener() { @SuppressLint("NewApi") @Override public void onClick(View arg0) { ibility(BLE); } }); }}效果：以上就是本⽂的全部内容，希望对⼤家的学习有所帮助，也希望⼤家多多⽀持。
