實現TextView中link的點擊效果，textviewlink

朋友們，你們在TextView處理link的時候是不是一直被苦逼的android預設的方式困擾？每次點擊link的時候，點擊效果是整個textview來響應。很爛吧？原因就不多贅述了。

那麼下面這個控制項就適合你了。 gitbub的連結：https://github.com/zhangjizxc/LinkClickTextView

好用的話，幫忙點個贊。

怎給textview添加一個點擊事件響應？

TextView txt = (TextView) findViewById(R.id.yourTextBoxId)); txt.setOnClickListener(new OnClickListener() { public void onClick(View view) { // USer Clicked the textBox } });
 
android TextView點擊事件

不會啊，剛試了， 在setOnClickListener上面下面加textView.setAutoLinkMask(Linkify.ALL)都可點，是導的View.OnClickListener嗎？
