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); } } |
