Android textview中的多个可点击字符串
我正在创建一个小型 Android 应用.我想在一个文本视图中显示一个文本，其中包含多个要单击的部分.(每个都应该显示一些不同的信息)
I am creating a small Android app. I would like to display a text in a textview with multiple parts to click on. (Each should show some different message)
最后我设法找出如何在一个文本视图中显示多个跨度，但不幸的是 onClick 方法不起作用.根本没有任何反应，甚至没有 logcat 行.
Finally I managed to find out how to display mutiple spans in one textview, however unfortunately the onClick methods don't work. Simply nothing happens, not even a logcat line.
我有这样的事情:
SpannableStringBuilder ssb=new SpannableStringBuilder();
ssb.append("first second")
ssb.setSpan(new ClickableSpan() {
@Override
public void onClick(View v) {
//Eredmeny2.this is just the context, name of the whole class
Toast.makeText(Eredmeny2.this, "first", Toast.LENGTH_LONG).show();
}
}, 1, 3, 0);
ssb.setSpan(new ClickableSpan() {
@Override
public void onClick(View v) {
Toast.makeText(Eredmeny2.this, "second", Toast.LENGTH_LONG).show();
}
}, 7, 10, 0);
TextView t1=new TextView(this);
t1.setText(ssb);
...
文本下划线很好，但是当我单击它们时没有任何反应.它是 TableView 的一部分，尽管我认为这无关紧要.你有什么想法为什么它什么都不做吗?我想念什么?还是我应该以完全不同的方式来做?
The text is underlined fine, but nothing happens when i click them. It is a part of a TableView, although I do not think this is relevant. Do you have any ideas why it does not do anything? What do I miss? Or should I do it on some totally different way?
提前致谢.
此部分将使用的布局文件如下:
The layout file this part would use is the following:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/ScrollView01"
android:background="#FF0000">
<TableLayout
android:id="@+id/TableLayout01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:stretchColumns="0"
android:showDividers="middle"
android:padding="3dp">
<TableRow
android:id="@+id/TableRow01"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="@+id/TextView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="3dp"
android:background="#000000"
android:textColor="#FFFFFF"
android:padding="6dp"
android:text="Hour"
android:textSize="20sp"
android:textStyle="bold" >
</TextView>
<TextView android:id="@+id/TextView02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:textStyle="bold"
android:text="Minute"
android:padding="6dp"
android:textColor="#FFFFFF"
android:background="#000000">
</TextView>
</TableRow>
</TableLayout>
</ScrollView>
而TextView直接使用的TextView布局如下:
And the TextView layout that the TextView uses directly is the following:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp"
android:background="#000000"
android:textIsSelectable="false"
android:textColor="#FFFFFF">
</TextView>
推荐答案
据我了解，您想让 textview 的多个部分可点击.
as i understand you want to make multiple part of textview clickable.
这段代码对我有用！
SpannableString ss = new SpannableString("this is a text");
ss.setSpan(new myClickableSpan(1),0, 4, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new myClickableSpan(2),5, 7, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new myClickableSpan(3),8, 10, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
mTextView.setText(ss);
mTextView.setMovementMethod(LinkMovementMethod.getInstance());
只需自定义 ClickableSpan 来处理点击事件
just make custom ClickableSpan to handle the click event
public class myClickableSpan extends ClickableSpan{
int pos;
public myClickableSpan(int position){
this.pos=position;
}
@Override
public void onClick(View widget) {
Toast.makeText(getApplicationContext(), "Position " + pos + " clicked!", Toast.LENGTH_LONG).show();
}
}
