Android控件各种属性设置

TextView设置中间或者底部横线

tv = (TextView) findViewById(R.id. text_view ); 
// 中间加横线 ， 添加Paint.ANTI_ALIAS_FLAG是线会变得清晰去掉锯齿
tv.getPaint().setFlags(Paint.STRIKE_THRU_TEXT_FLAG | Paint.ANTI_ALIAS_FLAG ); 
// 底部加横线 ， 添加Paint.ANTI_ALIAS_FLAG是线会变得清晰去掉锯齿
tv .getPaint().setFlags(Paint. UNDERLINE_TEXT_FLAG | Paint.ANTI_ALIAS_FLAG );

TextView设置字体加粗

android:textStyle="bold"

tv .setTypeface(Typeface.defaultFromStyle(Typeface.BOLD));//加粗
tv .setTypeface(Typeface.defaultFromStyle(Typeface.NORMAL));//取消加粗

设置drawable

        Drawable drawable = getContext().getResources().getDrawable(
                R.mipmap.icon_account_bind_down);
        drawable.setBounds(0, 0, drawable.getMinimumWidth(),
                drawable.getMinimumHeight());

        textView.setCompoundDrawables(null, null, drawable, null);
        textView.setCompoundDrawablePadding(DpUtils.dip2px(getContext(), 6));
