android LayoutInflater

 

<!--[if !supportLists]-->1      <!--[endif]-->android<!--[if !supportNestedAnchors]--><!--[endif]-->.view.LayoutInflater

 

LayoutInflater用于动态加载布局,实现XML布局文件转化为View视图。LayoutInflaterinflate方法就是用于将XML布局文件转化为View视图。有四种方式:

 

public android.view.View inflate(int resource, android.view.ViewGroup root)

 

public android.view.View inflate(org.xmlpull.v1.XmlPullParser parser, android.view.ViewGroup root)

 

public android.view.View inflate(int resource, android.view.ViewGroup root, boolean attachToRoot)

 

public android.view.View inflate(org.xmlpull.v1.XmlPullParser parser, android.view.ViewGroup root, boolean attachToRoot)

 

 

<!--[if !supportLists]-->1.1         <!--[endif]-->LayoutInflater获取方式

 

 

如果继承自android.app.FragmentFragment有个onCreateView方法,其第一个参数就是LayoutInflater

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)

通过这种方式就可以获得LayoutInflater

 

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)

 

LayoutInflater inflater = LayoutInflater.from(Activity.this)

 

LayoutInflater inflater = getLayoutInflater();

 

 

例子

 

public View getView(int position, View view, ViewGroup parent) {

       ImageView image = null;

       TextView title = null;

       TextView text = null;

       if (view == null || position < listData.size()) {

              view = LayoutInflater.from(mContext).inflate(R.layout.contacts_item, null);

              image = (ImageView) view.findViewById(R.id.ItemImage);

              title = (TextView) view.findViewById(R.id.ItemTitle);

              text = (TextView) view.findViewById(R.id.ItemText);

       }

       //绘制联系人名称

       title.setText((String) listData.get(position).get("ItemTitle"));

       //绘制联系人号码

       text.setText((String) listData.get(position).get("ItemText"));

       //绘制联系人头像

       image.setImageBitmap((Bitmap) listData.get(position).get("ItemImage"));

       return view;

}
