我有一个相对复杂的嵌套线性布局和文本视图设置，它们都是在运行时根据用户偏好创建的。
问题是启动应用程序需要大约五秒钟（智能手机时间的永恒）。
这是设置图。我在滚动视图中有大约 30 个红色线性布局，每个布局都包含 2 到 30 个紫色文本视图，它们包裹在 1 到 6 个橙色线性布局中。
我可以做些什么来加快这个 UI 的加载，或者保存它，以便当用户退出并重新打开应用程序时，它不必重新生成所有内容？
谢谢你。
我的代码在下面，它利用了这篇文章中的 populateLinks 函数。
public void displayUnits(){
LinearLayout ll = new LinearLayout(MainActivity.this);
ll = (LinearLayout) findViewById(R.id.fromunitslayout);
if (ll.getChildCount() > 3) {
ll.removeViewsInLayout(2,ll.getChildCount()-2);
}
fromunitlls = new ArrayList<LinearLayout>();
fromunitlls.clear();
int colorcount = 0;
for (int utcount = 0; utcount < unittypes.size(); utcount++) {
UnitType currenttype = null;
for (int typecount = 0; typecount < unittypes.size(); typecount++) {
if (unittypes.get(typecount).getOrder() == utcount) {
currenttype = unittypes.get(typecount);
Log.v("unittype disp", String.valueOf(unittypes.indexOf(currenttype)));
}
}
if (currenttype.getHidden() && !showallunits) {
continue;
}
for (int unitcount = 0; unitcount < ft.size(); unitcount++) {
if (ft.get(unitcount).getType().getID() == currenttype.getID()) {

llhorz.setBackgroundResource(R.color.DarkGreyT);
}
colorcount++;

txtTypeName.setTag("unittype" + unittypes.indexOf(currenttype));
txtTypeName.setPadding(5,0,5,0);
txtTypeName.setText(currenttype.getName().toUpperCase().replace(" ","\n"));
txtTypeName.setLayoutParams(new LayoutParams(140,LayoutParams.WRAP_CONTENT, Gravity.CENTER));
txtTypeName.setTextSize(12);
txtTypeName.setTypeface(Typeface.DEFAULT_BOLD);
txtTypeName.setGravity(Gravity.CENTER);
txtTypeName.setOnLongClickListener(new OnLongClickListener(){
public boolean onLongClick(View view){
String typenum = view.getTag().toString();
