TextView - OnClick - Android

标签: android textview

是否可以在文本视图的某些部分添加onclick?例如,我的代码是这样的,

String content = "Hello this a test.. For more details contact @Peter";
someTextView.setText(content);

我想为“@Peter”添加一个onClick事件。这可能吗?

TIA。

简单: - )

SpannableString link = makeLinkSpan("@Peter", new View.OnClickListener() {          
        @Override
        public void onClick(View v) {
            // Peforme Click
        }
    });
String content = "Hello this a test.. For more details contact";
someTextView.setText(content);
someTextView.append(link);

makeLinkSpan()方法是

private SpannableString makeLinkSpan(CharSequence text, View.OnClickListener listener) {
    SpannableString link = new SpannableString(text);
    link.setSpan(new ClickableString(listener), 0, text.length(), 
        SpannableString.SPAN_INCLUSIVE_EXCLUSIVE);
    return link;
}

ClickableString

private static class ClickableString extends ClickableSpan {  
    private View.OnClickListener mListener;          
    public ClickableString(View.OnClickListener listener) {              
        mListener = listener;  
    }          
    @Override  
    public void onClick(View v) {  
        mListener.onClick(v);  
    }        
}

在你的Xml中加上这个,android:clickable="true"

在你的活动中使用像这样,

textView.setOnClickListener(new View.OnClickListener(){
    public void onClick(){

    }
}

感谢@ user370305的回复。但是他在答案中错过了一些代码片段。为了别人的利益,我正在粘贴整个代码,对我有用,

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView someTextView = (TextView)findViewById(R.id.someTextView);

        String content = "Hello this a test.. For more details contact";
        someTextView.setText(content);

        SpannableString link = makeLinkSpan("@Peter", new View.OnClickListener() {          
                @Override
                public void onClick(View v) {
                    //Do something here..
                }
            });
            someTextView.append(link); 
        }
        makeLinksFocusable(someTextView);
    }

    private void makeLinksFocusable(TextView tv) {
        MovementMethod m = tv.getMovementMethod();  
        if ((m == null) || !(m instanceof LinkMovementMethod)) {  
            if (tv.getLinksClickable()) {  
                tv.setMovementMethod(LinkMovementMethod.getInstance());  
            }  
        }  
    }

    private SpannableString makeLinkSpan(CharSequence text, View.OnClickListener listener)                 {
        SpannableString link = new SpannableString(text);
        link.setSpan(new ClickableString(listener), 0, text.length(), 
            SpannableString.SPAN_INCLUSIVE_EXCLUSIVE);
        return link;
    }

    private static class ClickableString extends ClickableSpan {  
        private View.OnClickListener mListener;          
        public ClickableString(View.OnClickListener listener) {              
            mListener = listener;  
        }          
        @Override  
        public void onClick(View v) {  
            mListener.onClick(v);  
        }        
    }

这可能会使用Java代码:

someTextView.setOnClickListener(new View.OnClickListener(){
    public void onClick(){
        //Do Stuff
    }
});

但首先请确保将其设置为可点击。

someTextView.setClickable(true);

试试这个:

SpannableString str = new SpannableString("@Peter");
str.setSpan(new ClickableSpan() {

            @Override
            public void onClick(View widget) {
                // TODO Auto-generated method stub

            }
        }, 0, str.length(), Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

然后将str附加到TextView。

您还需要在TextView上调用setMovementMethod(LinkMovementMethod.getInstance());
