当按钮被点按时，如何使单击的按钮以一种颜色突出显示，并将所有其他按钮设置为一种颜色

Question

实际上，当我单击按钮时，我将有多个矩形按钮，我将获得列表视图。现在，当我单击按钮时，我需要用红色突出显示的颜色是什么问题，而其他所有按钮必须为绿色。 请帮助我。

活动：

if(name.isEmpty()||name==null){
    billnumber  +=name;
}
else{
    if(count==3){
        billnumber  +="  , "+name;
    }
    else if(count==2){
        billnumber  +="  , "+name;
    } 
    else if(count==1){
        billnumber  +=name;
    }
}


 if (count == 3) {
    id++;
    final Button dynamicTextView = new Button(this);
    dynamicTextView.setLayoutParams(new LayoutParams(350,
            LayoutParams.MATCH_PARENT));
    dynamicTextView.setBackgroundColor(Color.parseColor("#1c7900"));
    dynamicTextView.setText("Bill Numbers\n"+billnumber);
    dynamicTextView.setId(id);
    final Button dynamicinvnumber=new Button(this);


    if(id==(clickedid-1)){
        dynamicTextView.setBackgroundColor(Color
                        .parseColor("#cf0000"));
    }
    if(istouched){
    if (id == clickedid) {
        touchedlist=dynamicTextView.getText().toString();
        if(touchedlist.contains("Bill Numbers"))
        {
            touchedlist=touchedlist.replace("Bill Numbers","");
        }
        text=touchedlist;

        if(bumpedbillnumber!="0")
        {


            if(touchedlist.contains(bumpedbillnumber))
            {
                touchedlist=touchedlist.replace(bumpedbillnumber,"");
            }
            if(text.contains(bumpedbillnumber))
            {
                text=text.replace(bumpedbillnumber,"");
            }
        }
        dynamicTextView.setBackgroundColor(Color
                        .parseColor("#cf0000"));
    }
}
if(refreshlist!=1)
{
    if(id==1)
    {
        dynamicTextView.setBackgroundColor(Color
                        .parseColor("#cf0000"));
    }
}
if (invoice1 == null) {
    if (id ==1) {
        dynamicTextView.setBackgroundColor(Color
                .parseColor("#cf0000"));
    }

}
dynamicTextView.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 30);
dynamicTextView.setOnClickListener(new OnClickListener() {

    @SuppressWarnings("deprecation")
    @Override
    public void onClick(View v)
    {           
        EnabledButton = dynamicTextView.getId();
        clickedid=dynamicTextView.getId();

        dynamicTextView.setBackgroundColor(Color
                            .parseColor("#cf0000"));
        dynamicTextView.setSelected(true);
        invoiceToDisplay = null;
        invoiceToDisplay = new ArrayList<String>();
        text = dynamicTextView.getText().toString();
        if(text.contains("Bill Numbers"))
        {
            text=text.replace("Bill Numbers","");
        }
        String s[] = text.split("  , ");

        invoice = text.split("  , ");
        System.out.println("s" + s[0]);
        istouched=true;
        refreshlist=1;
        if (s.length == 1) {

            if(s[0].contains("\n"))
            {
                s[0]=s[0].replace("\n","");
            }
            int invoice11=receiptlist.indexOf(s[0].trim());
            String invoiceselected=invoiceList.get(invoice11);

            tv1.setVisibility(View.GONE);
            tv2.setVisibility(View.GONE);
            tv.setVisibility(View.VISIBLE);
            footerText3.setVisibility(View.GONE);

Drawable Xml：

btn_selected.xml

   <?xml version="1.0" encoding="utf-8"?>
  <shape xmlns:android="http://schemas.android.com/apk/res/android" 
  android:shape="rectangle">
     <solid android:color="red_color"/>
 </shape>

btn_un_selected.xml

  <?xml version="1.0" encoding="utf-8"?>
  <shape xmlns:android="http://schemas.android.com/apk/res/android" 
  android:shape="rectangle">
     <solid android:color="ordinary_color"/>
 </shape>

btn_selector

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >

 <item android:drawable="@drawable/btn_selected"  android:state_selected="true"></item>

 <item android:drawable="@drawable/btn_selected"  android:state_pressed="true"/>
 <item android:drawable="@drawable/btn_un_selected"/>
</selector>

在xml中更改按钮的按钮背景

<Button 
........
android:background="@drawable/btn_selector/>

在代码更改

btn.setSelected(!btn.isSelected);

无需以编程方式创建按钮，而是在xml上创建它们，然后在您的活动中检索其ID，以便您可以访问它们； 在为他们设置set onTouchListener之后，并在其中进行设置。

将Rect rect和shouldPerformClick定义为活动的全局变量。

button1.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getActionMasked()){
                case MotionEvent.ACTION_DOWN:
                    changeButtonBackgrounds(v.getId());
                    shouldPerformClick = true;
                    break;
                case MotionEvent.ACTION_MOVE:
                    rect = new Rect();
                    v.getDrawingRect(rect);
                    if(!(rect.left < event.getX() && event.getX() < rect.right)){
                        shouldPerformClick = false;
                        resetButtonBackgrounds();
                    }
                    if(!(rect.bottom < event.getY() && event.getY() < rect.top)){
                        shouldPerformClick = false;
                        resetButtonBackgrounds();
                    }
                    break;
                case MotionEvent.ACTION_UP:
                    resetButtonBackgrounds();
                    if(shouldPerformClick){
                        button1.performClick;
                    }
                    break;
            }
            return true;
        }
    });

我会在changeButtonBackgrounds（）上使用switch（viewID），我认为我的整个方法需要更多样板，但它更理想。

定义按钮数组buttons ，这些按钮是XML文件中的按钮，并且是一个全局变量int selectedIndex=0 。

确保在XML文件中，所有按钮均为绿色。

selectedIndex将是最后一个选定按钮的数组中的索引。

然后，在数组中的每个按钮上

    for (int i = 0 ; i < buttons.length ; i++)
        buttons[i].setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                buttons[selectedIndex]
                        .setBackgroundTintList(ColorStateList.valueOf(getResources()
                                .getColor(R.color.green, getTheme())));


                switch (view.getId()) {

                    case R.id.button1:
                        buttons[0].setBackgroundTintList(ColorStateList.valueOf(getResources()
                                .getColor(R.color.red)));
                        selectedIndex = 0;
                        break;

                    case R.id.button2:
                        buttons[1].setBackgroundTintList(ColorStateList.valueOf(getResources()
                                .getColor(R.color.red)));
                        selectedIndex = 1;
                        break;

                    .
                    .
                    .
                }

            }
        });
