I had the same problem and wanted to have more than one clickable links in the text of a checkbox without loosing the ability to click anywhere in the text (where there is no URL) to select/deselect the checkbox.
对这一问题的其他答案的区别在于,通过这一解决办法,你可以在检查箱文本中有多个可点击的链接,这些链接不必在文本末尾。
布局类似于。 回答:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="16dp">
<CheckBox
android:id="@+id/tosCheckBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:checked="false" />
<TextView
android:id="@+id/tosTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/tosCheckBox"
android:layout_centerVertical="true"
android:clickable="true" />
</RelativeLayout>
我现在以方案方式确定案文。 我要表明的案文是:
"I have read and accepted the <a href= https://www.anyurl.com/privacy >privacy statement</a> and <a href= https://www.anyurl.com/tos >terms of service.</a>"
由于它包含的是超文本,我首先将其改为Spanned。 为了点击这些链接,我还确定了文本意见与链接的移动方法:
mTosTextView = (TextView) findViewById(R.id.tosTextView);
mTosTextView.setText(Html.fromHtml(getString(R.string.TOSInfo)));
mTosTextView.setMovementMethod(LinkMovementMethod.getInstance());
这里是比较trick的。 迄今为止,在发出文本意见时,并未选定支票。 为了做到这一点,我给案文增加了一个触动手:
mTosCheckBox = (CheckBox) findViewById(R.id.tosCheckBox);
mTosTextView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
CharSequence text = mTosTextView.getText();
// find out which character was touched
int offset = getOffsetForPosition(mTosTextView, event.getX(), event.getY());
// check if this character contains a URL
URLSpan[] types = ((Spanned)text).getSpans(offset, offset, URLSpan.class);
if (types.length > 0) {
// a link was clicked, so don t handle the event
Log.d("Some tag", "link clicked: " + types[0].getURL());
return false;
}
// no link was touched, so handle the touch to change
// the pressed state of the CheckBox
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
mTosCheckBox.setPressed(true);
break;
case MotionEvent.ACTION_UP:
mTosCheckBox.setChecked(!mTosCheckBox.isChecked());
mTosCheckBox.setPressed(false);
break;
default:
mTosCheckBox.setPressed(false);
break;
}
return true;
}
});
最后,正如你可能注意到的那样,目前还没有办法<条码>。 如果你重新瞄准第14+级,你可以简单地使用getOffsetForPosition(>,指出。 由于我的目标是第8+级,我使用了我在这里看到的“执行”:。
public int getOffsetForPosition(TextView textView, float x, float y) {
if (textView.getLayout() == null) {
return -1;
}
final int line = getLineAtCoordinate(textView, y);
final int offset = getOffsetAtCoordinate(textView, line, x);
return offset;
}
private int getOffsetAtCoordinate(TextView textView2, int line, float x) {
x = convertToLocalHorizontalCoordinate(textView2, x);
return textView2.getLayout().getOffsetForHorizontal(line, x);
}
private float convertToLocalHorizontalCoordinate(TextView textView2, float x) {
x -= textView2.getTotalPaddingLeft();
// Clamp the position to inside of the view.
x = Math.max(0.0f, x);
x = Math.min(textView2.getWidth() - textView2.getTotalPaddingRight() - 1, x);
x += textView2.getScrollX();
return x;
}
private int getLineAtCoordinate(TextView textView2, float y) {
y -= textView2.getTotalPaddingTop();
// Clamp the position to inside of the view.
y = Math.max(0.0f, y);
y = Math.min(textView2.getHeight() - textView2.getTotalPaddingBottom() - 1, y);
y += textView2.getScrollY();
return textView2.getLayout().getLineForVertical((int) y);
}
