LayoutInflater功用是将layout的xml布局文件实例化为View类对象
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);
}
}
