android:autolink 颜色,Android设置完autoLink属性后自定义跳转到指定界面

在TextView 中设置autoLink 属性可以自动识别Web

URL,电话号码，电子邮件地址添加下划线改变字体颜色并实现点击事件，支持自动识别的类型：

android:autoLink=“web” 匹配Web URL。

android:autoLink=“phone” 匹配电话号码

android颜色对照表、android:autoLink=“email” 匹配电子邮件地址

android:autoLink=“map” 匹配地理位置

android:autoLink=“all” 匹配所有可用的模式

android:autoLink=“none” 不匹配任何类型

也可以类似这样的设置 android:autoLink=“web|phone” 表示匹配web URL 和手机号

如何修改Android文件属性、上面的属性也可以通过java 代码的形式对TextView 设置

setAutoLinkMask(int mask) 进行设置

1

设置的参数分别是：

Linkify.WEB_URLS 匹配Web UR

android的属性有什么作用。Linkify.PHONE_NUMBERS 匹配电话号码

Linkify.EMAIL_ADDRESSES 匹配电子邮件地址

Linkify.MAP_ADDRESSES 地理位置匹配

Linkify.ALL 匹配所有可用的模式

设置完antoLink属性，点击TextView中的链接时会跳转的对应的界面，比如点击网页的链接会跳转到系统的默认的浏览器界面，点击手机号会进入拨打电话界面，但是这都是系统默认的，我们可不可以进行拦截处理，跳转到我们指定的界面呢，当然是可以的。下面是我的拦截处理的方法。

android如何设置窗口属性、继承 MovementMethod ，这里我们先看一下MovementMethod的源码，它的源码比较少

public class LinkMovementMethod extends

ScrollingMovementMethod {

private static final int

CLICK = 1;

android用代码设置颜色？private static final int

UP = 2;

private static final int

DOWN = 3;

@Override

android中view属性？public boolean

canSelectArbitrarily() {

return true;

}

@Override

android获取xml属性。protected boolean

handleMovementKey(TextView widget, Spannable buffer, int

keyCode,

int

movementMetaState, KeyEvent event) {

auto layout，switch (keyCode) {

case

KeyEvent.KEYCODE_DPAD_CENTER:

case

KeyEvent.KEYCODE_ENTER:

android 颜色 灰色，if

(KeyEvent.metaStateHasNoModifiers(movementMetaState)) {

if (event.getAction() == KeyEvent.ACTION_DOWN

&&

event.getRepeatCount() == 0

android auto怎么用？&& action(CLICK, widget, buffer)) {

return

true;

}

}

break;

}

return super.handleMovementKey(widget, buffer,

keyCode, movementMetaState, event);

}

@Override

protected boolean

up(TextView widget, Spannable buffer) {

return super.left(widget, buffer);

}

@Override

protected boolean

right(TextView widget, Spannable buffer) {

if (action(DOWN, widget, buffer)) {

}

return super.right(widget, buffer);

}

private boolean

action(int what, TextView widget, Spannable buffer) {

Layout layout = widget.getLayout();

在上面的这段代码中处理界面跳转的只有这一行

links[0].onClick(widget);我们要实现自己的跳转只要在自定义的LinkMovementMethod的这一行进行处理就行了。

先定义一个替换links[0].onClick(widget);的接口

public interface LinkClickListener {

boolean

onLinkClick(String mURL);

}

定义一个LinkMovementMethod的子类

LinkMovementMethodEx，在onTouchEvent方法中做了判断，在我们应用自己处理的情况，就不在走系统的默认处理，只有我们自己不处理的情况下才走系统的。

public class LinkMovementMethodEx extends LinkMovementMethod

{

private

LinkClickListener listener;

public

LinkMovementMethodEx(LinkClickListener listener) {

this.listener = listener;

}

@Override

public boolean

onTouchEvent(TextView widget, Spannable buffer, MotionEvent event)

{

int action = event.getAction();

if (action == MotionEvent.ACTION_UP || action ==

MotionEvent.ACTION_DOWN) {

int x =

(int) event.getX();

int y =

(int) event.getY();

x -=

widget.getTotalPaddingLeft();

y -=

widget.getTotalPaddingTop();

x +=

widget.getScrollX();

y +=

widget.getScrollY();

Layout

layout = widget.getLayout();

int line =

layout.getLineForVertical(y);

int off =

layout.getOffsetForHorizontal(line, x);

ClickableSpan[] links = buffer.getSpans(off, off,

ClickableSpan.class);

if

(links.length != 0) {

if (action ==

MotionEvent.ACTION_UP) {

if (links[0] instanceof URLSpan) {

URLSpan

url = (URLSpan) links[0];

if

(listener != null && listener.onLinkClick(url.getURL()))

{

return true;

} else

{

links[0].onClick(widget);

}

}

} else if (action ==

MotionEvent.ACTION_DOWN) {

Selection.setSelection(buffer,

buffer.getSpanStart(links[0]),

buffer.getSpanEnd(links[0]));

}

return true;

} else

{

Selection.removeSelection(buffer);

}

}

return super.onTouchEvent(widget, buffer,

event);

}

}

在项目中的引用

public class MainActivity extends Activity {

private String TAG =

MainActivity.class.getSimpleName();

private TextView

title;

@Override

protected void

onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

title = findViewById(R.id.tv_content);

title.setText(" 10086 中国移动的 这是百度的

https://www.baidu.com/");

title.setMovementMethod(new

LinkMovementMethodEx(new LinkClickListener() {

@Override

public

boolean onLinkClick(String mURL) {

//在这里执行直接的处理逻辑并将返回值设置为true

Log.i(TAG, "onLinkClick: " +

mURL);

return false;

}

}));

}

}
