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:
//第一种
LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.main, null);
//第二种
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);
//第三种
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);
}
}
