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。LayoutInflater中inflate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.Fragment，Fragment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; }
