android中的spanableString的背景颜色

Question

我只使用一个文本视图并使用spanable为字符串添加字体和颜色.但我有问题,使用spanable显示圆形背景到字符串.那么如何使用spannable String概念实现这一目标,图像如下所示.

Answer 1

您可以使用的文本视图的冷杉背景颜色

String myString = "myString";
Spannable spanna = new SpannableString(myString);
spanna.setSpan(new BackgroundColorSpan(0xFFCCCCCC),0, myString.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);           
myTextView.setText(spanna);

对于舍入的文本视图,创建自定义XML并将背景设置为该textview.

创建一个名为rounded-corner.xml的 XML 并设置此内容

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

    <!-- view background color -->
    <solid android:color="#ffffff" >
    </solid>

    <!-- view border color and width -->
    <stroke
        android:width="1dp"
        android:color="#1c1b20" >
    </stroke>

    <!-- If you want to add some padding -->
    <padding
        android:bottom="4dp"
        android:left="4dp"
        android:right="4dp"
        android:top="4dp" >
    </padding>

    <!-- Here is the corner radius -->
    <corners android:radius="10dp" >
    </corners>

</shape>

然后将此行添加到XML中的textview

android:background="@drawable/rounded_corner"

我已经实现了上面的用户界面，如下所示。创建了水平滚动视图和一个水平方向的线性布局。接下来，在运行时，根据数组中的字符串数量，我在线性布局中添加了文本视图，就是这样。代码如下。

    private void addTextView(ArrayList<String> list,String whichLayout){

    for (int i = 0; i < list.size(); i++) {
         TextView textView = new TextView(getActivity());
         Spannable spValue = new SpannableString(list.get(i).toString());
         textView.setText(customeSpan.getRequiredFontTypeToText(spValue, tfHintTxtValue));
         textView.setTextSize(12.0f);
         textView.setTextColor(getResources().getColor(R.color.black));
         textView.setBackgroundResource(R.drawable.red_solid_background);
         LinearLayout.LayoutParams lllp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
         lllp.setMargins(0, 2, 10, 0); // llp.setMargins(left, top, right, bottom);
         textView.setLayoutParams(lllp);
         if(whichLayout.equalsIgnoreCase("hieghtWieght")){
             ((LinearLayout) heightWieghtLinearLayout).addView(textView);
         }else if(whichLayout.equalsIgnoreCase("bodyType")){
             ((LinearLayout) bodyTypeLinearLayout).addView(textView);
         }else if(whichLayout.equalsIgnoreCase("eyeHair")){
             ((LinearLayout) eyeHairColorLinearLayout).addView(textView);
         }else if(whichLayout.equalsIgnoreCase("bestFeatures")){
             ((LinearLayout) bestFeaturesLinearLayout).addView(textView);
         }else if(whichLayout.equalsIgnoreCase("personalStyle")){
             ((LinearLayout) personalStyleLinearLayout).addView(textView);
         }else if(whichLayout.equalsIgnoreCase("zodiacSign")){
             ((LinearLayout) zodizcSignLinearLayout).addView(textView);
         }else if(whichLayout.equalsIgnoreCase("personalityTraits")){
             ((LinearLayout) personalityLinearLayout).addView(textView);
         }  
    }
}
