How to use Html rendering to implement the * sign in front of required fields in Android

This article mainly introduces the use of Html rendering in android to implement the * example in front of the required fields. It has certain reference value. Those who are interested can learn about the personal basic information UI of the

project. The interface rendering is as follows. There is a red * sign, and it is a different color from the text next to it. Jane friends, how did you achieve it? Here I mainly introduce a method of Html rendering

#At the beginning, I tested using a TextView to load the conformity separately, and found that if the color needs to be changed, Then all TextViews needed to change their colors. Then I tested using a TextView to load matching and corresponding text together, but found that the height of the * symbol was difficult to control. Finally, I felt that using Html rendering was the best way. Without further ado, let’s start with the main text.

1. Xml layout (select only the corresponding part)

The * symbol and text here actually share a TextView

 <LinearLayout
    style="@style/style_match_line_layout"
    android:layout_marginTop="10dp" >

<!--主要看这个TextView-->
    <TextView
     android:id="@+id/tv_nation"
     style="@style/style_job_textview_text_title"
     tools:text="*民族"
     android:text="@string/tip_nation" />


    <RelativeLayout
     android:id="@+id/view_nation"
     style="@style/style_job_textview_text_message"
     android:clickable="true" >

     <EditText
      android:id="@+id/et_nation"
      style="@style/style_editext"
      android:hint="@string/tip_please_select" />

     <ImageView style="@style/style_editext_image_arrow" />
    </RelativeLayout>
 </LinearLayout>

2. Create the corresponding String resource

Here you can set the color and boldness of the * symbol and text separately

Copy code The code is as follows:

<string name="tip_xinghao_nation"><Data><![CDATA[<font color="#e60012"> *</font><font color="#189dde">民族 : </font>]]></Data></string>

3. Implement rendering in java code

tvNation.setText(Html.fromHtml(getString(R.string.tip_xinghao_nation)));

Go here You can achieve the effect in the rendering. If you change the color and size of the * symbol and text, you can change it uniformly in the String resource.
