使用replace(CharSequence target, CharSequence replacement)String中的方法,如何使目标不区分大小写？

例如,它现在的工作方式:

String target = "FooBar";
target.replace("Foo", "") // would return "Bar"

String target = "fooBar";
target.replace("Foo", "") // would return "fooBar"

我怎样才能使它如此替换(或者如果有更合适的方法)是不区分大小写的,这样两个例子都返回"Bar"？

如何忽略以下示例中的大小写？

outText = inText.replaceAll(word, word.replaceAll(" ", "~"));

例:

输入:

inText = "Retail banking Wikipedia, the free encyclopedia Retail banking "
       + "From Wikipedia. retail banking industry."

word   = "retail banking"

产量

outText = "Retail~banking Wikipedia, the free encyclopedia Retail~banking " +
          "From Wikipedia. retail~banking industry."

嗨朋友我正在创建一个应用程序.
我想找到一个特定的单词ArrayList,我必须
用另一个单词替换它.我使用下面的代码.它的工作区分大小写,
但我想让它工作区不敏感.

   FillintheBlank.class: 

          public class FillintheBlank extends Activity {
        static ArrayList<String> multiword=new ArrayList<String>();

 static ArrayList<String> multimeaning=new ArrayList<String>();


public void setNoTitle() {
    requestWindowFeature(Window.FEATURE_NO_TITLE);
} 
 float screenHeight,screenWidth,screendensity;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
     setNoTitle();
     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
     DisplayMetrics displaymetrics = new DisplayMetrics();
     getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
     screenHeight = displaymetrics.heightPixels;
     screenWidth = displaymetrics.widthPixels;
     screendensity = displaymetrics.densityDpi;
    setContentView(R.layout.fillinblanknew);

             multiword.add("radha");
             multiword.add("RAdHA");
              multiword.add("latha");
                multiword.add("mammu");

              s.o.p(""+multiword);
            // output:radha,RADHA,latha,mamu

          multimeaning.add(multiword.getString().replace(radha,"sai"));
        s.o.p(""+multimeaning);
     // output: sai,RADHA,latha,mamu

 }
  } 

例如:无论'radha'中的字母是什么,我都需要用'sai'替换'radha'.
