Android View layoutInflater 通过字符串获取布局

Question

在 android 上通过使用动态字符串作为 id 来获取带有 layoutInflater 的 View 时遇到问题。

此代码有效：

LayoutInflater layoutInflater = (LayoutInflater) 
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View newView = layoutInflater.inflate(R.layout.my_layout, null);
scrollViewMain.removeAllViews();
scrollViewMain.addView(newView);

但我想通过使用这样的字符串来动态获取视图：

String myString = "my_layout";
LayoutInflater layoutInflater = (LayoutInflater) 
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View newView = layoutInflater.inflate(R.layout.myString, null);
scrollViewMain.removeAllViews();
scrollViewMain.addView(newView);

感谢您帮助理解这一点。

Answer 1

String myString = "my_layout";

int layout_id= context.getResources().getIdentifier(
    myString,
    "layout",
    context.getPackageName()
);

LayoutInflater layoutInflater = (LayoutInflater) 
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View newView = layoutInflater.inflate(layout_id, null);
scrollViewMain.removeAllViews();
scrollViewMain.addView(newView);
