LayoutInflater作用是将layout的xml布局文件实例化为View类对象。
获取LayoutInflater的方法有如下三种:LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);View layout = inflater.inflate(R.layout.main, null);LayoutInflater inflater = LayoutInflater.from(context); (该方法实质就是第一种方法,可参考源代码)View layout = inflater.inflate(R.layout.main, null);LayoutInflater inflater = getLayoutInflater();(在Activity中可以使用,实际上是View子类下window的一个函数)View layout = inflater.inflate(R.layout.main, null);使用方法:public class MyInflate extends Activity{private TextView tv;public void OnCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);//setContentView(R.layout.main);//tv = (TextView) findViewById(R.id.tv);LayoutInflater inflate = LayoutInflater.from(this);View view = inflate.inflate(R.layout.main,null);setContentView(view);}}
