TextView的深入使用

               

               TextView test = (TextView)findViewById(R.id.test);

// 创建一个 SpannableString对象
SpannableString sp = new SpannableString("这句话中有百度超链接,有高亮显示，这样，或者这样，还有斜体.已经跳转到新的Activity");
// 设置超链接
sp.setSpan(new URLSpan("http://www.baidu.com"), 5, 7, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
// 设置高亮样式一
sp.setSpan(new BackgroundColorSpan(Color.RED), 17, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
// 设置高亮样式二
sp.setSpan(new ForegroundColorSpan(Color.YELLOW), 20, 24, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
// 设置斜体
sp.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC), 27, 29, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
// SpannableString对象设置给TextView
sp.setSpan(new UnderlineSpan(), 0, 9, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//设置下划线
sp.setSpan(new StrikethroughSpan(), 7, 11, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); 
//设置删除线
sp.setSpan(new URLSpan("tel:[phone]"), 7, 11, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); 

Intent intent = new Intent(this, Test2Activity.class);  
sp.setSpan(new IntentSpan(intent), 30, 38, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);  

test.setText(sp);
// 设置TextView可点击

test.setMovementMethod(LinkMovementMethod.getInstance());

IntentSpan的代码：

public class IntentSpan extends ClickableSpan implements ParcelableSpan {
private final Intent mIntent;


    public IntentSpan(Intent intent) {
    mIntent = intent;
    }
    
    public int getSpanTypeId() {
        return 100;
    }
    
    public int describeContents() {
        return 0;
    }


    public Intent getIntent() {
        return mIntent;
    }


    public void writeToParcel(Parcel dest, int flags) {
}
    
    public void onClick(View widget) {
        Context context = widget.getContext();
        context.startActivity(mIntent);
    }

}
