TextView

Width 绘制分析

没有其他属性影响的话，宽度应该就是字体的宽度，在横向的recycleview adater中不同的字体会增加间距。

android:autoSizeTextType="uniform"
android:autoSizeMinTextSize="8sp"
android:autoSizeMaxTextSize="12sp"
android:autoSizeStepGranularity="1sp"

TextView颜色变化

SpannableString

https://juejin.im/entry/5729d28f1ea49300606854c9
SpannableString有一个不方便的地方是截取字符串

    TextView tvRegister = findViewById(R.id.tv_register);
      //将TextView的显示文字设置为SpannableString
​	    tvRegister.setText(getClickableSpan());
​	    //设置该句使文本的超连接起作用
​	    tvRegister.setMovementMethod(LinkMovementMethod.getInstance());
​	    
​	   private SpannableString getClickableSpan() {
​	    SpannableString spanTxt = new SpannableString("阅读并同意<<用户注册协议>>");
​	    //设置文字的前景色
​	    spanTxt.setSpan(new ForegroundColorSpan(Color.GREEN),5, 15,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
​	    spanTxt.setSpan(new ClickableSpan() {	
​	        @Override
​	        public void onClick(View widget) {
​	            Intent intent = new Intent(TextViewActivity.this, FirstActivity.class);
​	            startActivity(intent);
​	        }
​	    }, 5, 15, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
​

Html标签方式

TextView textView = (TextView) findViewById(R.id.text_for_test);
String textSource = "修改TextView中部分文字的<font color='#ff0000'><big>大</big><small>小</small></font>和<font color='#00ff00'>颜色</font>，展示多彩效果！";
textView.setText(Html.fromHtml(textSource));
