TextView
android:textAlignment="center"
android:textColorHint="#adadad"
textAllCaps 在xml布局中把默认的大写改成小写
mTvMarketPrice.getPaint().setFlags(Paint. STRIKE_THRU_TEXT_FLAG);设置中划线
TextView限制文字个数，过多设置省略号
android:maxEms="12"
android:ellipsize="end"
android:maxLines="1"
CBAlignTextView【调整排版】
AutofitTextView【根据字体长度调整字体大小】
