protected void onResume() {
<span style="white-space:pre"> </span>super.onResume();
<span style="white-space:pre"> </span>initTopLayout(this);
<span style="white-space:pre"> </span>Log.i("BaseActivity", "onResume");
<span style="white-space:pre"> </span>setTop(leftBtn, titleTv, rightTv, rightIv);
<span style="white-space:pre"> </span>}子类在执行到onResume方法的时候调用父类的onResume方法，此时方法initTopLayout中的参数为子类的实例在方法initTopLayout中就可以得到子类布局中的各个控件。public void initTopLayout(Activity act) {
RelativeLayout rlTop = (RelativeLayout) act.findViewById(R.id.base_top);
if (rlTop == null) {
throw new RuntimeException("please inlucde layout common_title in Ur layout,and make sure the include id is @+id/common_title @+id/base_top");
}
this.leftBtn = (Button) rlTop.findViewById(R.id.btn_globaltop_leftbutton);
this.titleTv = (TextView) rlTop.findViewById(R.id.tv_globaltop_title);
this.rightTv = (TextView) rlTop.findViewById(R.id.tv_globaltop_righttext);
this.rightIv = (ImageView) rlTop.findViewById(R.id.iv_globaltop_rightiv);
}public void setTop(Button leftBtn, TextView titleTv, TextView rightTv, ImageView rightIv) {
super.setTop(leftBtn, titleTv, rightTv, rightIv);
enableBackBtn();
rightIv.setVisibility(View.VISIBLE);
rightIv.setImageResource(R.drawable.ibtn_selector_share);
rightIv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO:share
}
});
}同理的还有BaseFragment等的应用，也可以参照这种方法实现精简代码结构。<include>标签和BaseActivity联合使用简化代码结构
