Question

Android Studio如果在java中编写布局，代码放在哪个文件中？什么位置？

Answer 1

1.使用代码编写一个底部选项卡的布局
2.整个页面的容器布局（包含Fargment,分割线，选项卡）
private void initView(Context context) {
setBackgroundColor(0xfff6f6f6);
FrameLayout frameLayout=new FrameLayout(context);//选项界面容器
frameLayout.setId(FL_ID);
View lineView=new View(context);//分割线
lineView.setId(LINE_ID);
RelativeLayout.LayoutParams rlParams=new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
rlParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
rlParams.addRule(RelativeLayout.ABOVE , LINE_ID);
lineView.setBackgroundColor(lineColor);
RelativeLayout.LayoutParams rlParams2=new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, DensityUtils.dip2px(context, 1));
rlParams2.addRule(RelativeLayout.ABOVE , TAB_ID);
addView(frameLayout, rlParams);//选项界面容器
addView(lineView,rlParams2);//分割线
//选项卡容器
linearLayout=new LinearLayout(context);
linearLayout.setBackgroundColor(tabBgColor);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
linearLayout.setGravity(Gravity.CENTER_VERTICAL);
linearLayout.setId(TAB_ID);
tabNum=tabIcos.length;
for (int i = 0; i < tabNum; i++) {
View view = createIndicator(tabIcos[i], tabtxts[i], tabItemTvColor, "itemTag"+i, "icoTag" + i, "txtTag" + i);
view.setOnClickListener(OnClick);
if(i== nowTabIndex){//初始化选项卡
changeTab(view, i);
}
