我怎样能够在TextView中实现多个可点击的文本部分,每个可点击部分都有自己的动作。
你可以使用android.text.style.ClickableSpan
SpannableString ss = new SpannableString("Hello World");
ClickableSpan span1 = new ClickableSpan() {
@Override
public void onClick(View textView) {
// do some thing
}
};
ClickableSpan span2 = new ClickableSpan() {
@Override
public void onClick(View textView) {
// do another thing
}
};
ss.setSpan(span1, 0, 4, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(span2, 6, 10, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setText(ss);
textView.setMovementMethod(LinkMovementMethod.getInstance());
我将主要文本和可点击单词存储在不同的资源中。
某些配置下,资源中不存在字符串。
String[] links = new String[3];
links[0] = cntx.getString(cntx.getResources().getIdentifier("footerLink1", "string", cntx.getPackageName()));
links[1] = cntx.getString(cntx.getResources().getIdentifier("footerLink2", "string", cntx.getPackageName()));
links[2] = cntx.getString(cntx.getResources().getIdentifier("footerLink3", "string", cntx.getPackageName()));
String text = String.format(cntx.getString(cntx.getResources().getIdentifier("footerDisclaimer", "string", cntx.getPackageName())), links[0], links[1], links[2]);
SpannableString ss = new SpannableString(text);
setSpanOnLink(ss, links[0], new ClickableSpan() {
@Override
public void onClick(View textView) {
Log.i("Disclaimer Footer", "1 click");
//TODO run item
}
});
setSpanOnLink(ss, links[1], new ClickableSpan() {
@Override
public void onClick(View textView) {
Log.i("Disclaimer Footer", "2 click");
//TODO run item
}
});
setSpanOnLink(ss, links[2], new ClickableSpan() {
@Override
public void onClick(View textView) {
Log.i("Disclaimer Footer", "3click");
//TODO run item
}
});
TextView t1 = new TextView(cntx);
t1.setTextSize(TypedValue.COMPLEX_UNIT_SP, 8);
t1.setText(ss);
t1.setMovementMethod(LinkMovementMethod.getInstance());
private void setSpanOnLink(SpannableString ss, String link, ClickableSpan cs) {
String text = ss.toString();
int start = text.indexOf(link);
int end = start + link.length();
ss.setSpan(cs, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
<TextView
android:id="@+id/tv_by_continuing_str"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:textSize="15sp"
tools:text="Test msg 1 2, 3"
android:textColor="@color/translucent_less_white3"
android:textColorLink="@color/white"
android:gravity="center|bottom"
android:layout_above="@+id/btn_privacy_continue" />
在 strings.xml 文件中
< string name="by_continuing_str2">< ! [ CDATA[By continuing to use this app, you agree to our <a href="https://go.test.com" style="color:gray"/> Privacy Statement </a> and <a href="https://go.test.com" style="color:gray"/>Services Agreement.]]>< / string>
在活动中:
TextView tv_by_continuing = (TextView) findViewById(R.id.tv_by_continuing);
tv_by_continuing.setText(Html.fromHtml(getString(R.string.by_continuing_str2)));
tv_by_continuing.setMovementMethod(LinkMovementMethod.getInstance());
