android - 使部分 TextView 可点击(不是 url)

Question

我已经挣扎了一段时间了。在需要文本的 Activity 上:单击注册，即表示我同意服务条款和隐私政策。“服务条款”和“隐私政策”部分需要可点击。我找到的解决方案制作了 url。但我不需要 url 来浏览条款，需要启动条款 Activity 或隐私 Activity 。

然后我发现了这个: https://stackoverflow.com/a/9076448/1387161但这里的问题是，它们并没有很好地对齐。我的意思是:如果有小分辨率的手机，我需要在textview2 旁边设置textview1，在textview1 下设置textview3，旁边是textview4。但是当我在平板电脑或屏幕更大的手机上使用该应用程序时，也许所有的 TextView 都可以彼此相邻，但布局与屏幕较小的手机相同 =

TextView 1 - TextView 2Textview3 - Textview4

一个可能的解决方案是流式布局，但我遇到了错误并且似乎找不到好的教程(适合初学者) How to use flowlayout (or any custom layout)

欢迎任何想法!

谢谢，

public class MainActivity extends Activity {
TextView _tv;


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    _tv = (TextView) findViewById( R.id.textView1 );
    String sentence = "this is [part 1 clickable] and [part 2 clickable] and [part 3 clickable]";


   _tv.setMovementMethod(LinkMovementMethod.getInstance());
   _tv.setText(addClickablePart(sentence), BufferType.SPANNABLE);
}
private SpannableStringBuilder addClickablePart(String str) {
    SpannableStringBuilder ssb = new SpannableStringBuilder(str);

    int idx1 = str.indexOf("[");
    int idx2 = 0;
    while (idx1 != -1) {
        idx2 = str.indexOf("]", idx1) + 1;

        final String clickString = str.substring(idx1, idx2);
        ssb.setSpan(new ClickableSpan() {

            @Override
            public void onClick(View widget) {
                Toast.makeText(MainActivity.this, clickString,
                        Toast.LENGTH_SHORT).show();
            }
        }, idx1, idx2, 0);
        idx1 = str.indexOf("[", idx2);
    }

    return ssb;
 }
}

public class MainActivity extends Activity {
TextView _tv;


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    _tv = (TextView) findViewById( R.id.textView1 );

    SpannableString ss = new SpannableString("Android is a Software stack");

    ss.setSpan(new MyClickableSpan(), 22, 27, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//22 to 27 stack is clickable
    ss.setSpan(new MyClickableSpan(), 0, 7, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//0 to 7 Android is clickable

   _tv.setText(ss);
   _tv.setMovementMethod(LinkMovementMethod.getInstance());
}
class MyClickableSpan extends ClickableSpan{ //clickable span
    public void onClick(View textView) {
    //do something
       Toast.makeText(MainActivity.this, "Clicked",
            Toast.LENGTH_SHORT).show();
   }
    @Override
    public void updateDrawState(TextPaint ds) {
       ds.setColor(Color.GREEN);//set text color 
       ds.setUnderlineText(false); // set to false to remove underline
    }
}
}

您还可以通过将其设置为粗体、斜体或设置字体大小来设置可跨越字符串的样式。

    StyleSpan boldSpan = new StyleSpan( Typeface.ITALIC );
    ss.setSpan( boldSpan, 22, 27, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE );
    StyleSpan boldSpan1 = new StyleSpan(Typeface.BOLD);
    ss.setSpan(new RelativeSizeSpan(3f), 0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);//set fontsize
    ss.setSpan( boldSpan1, 0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE );
