onclick

I have a listview which is build up of two textviews coming from a separate layout file. I use a BaseAdapter to build the list from a JSON file. I would like the first textview (Caption) to be clickable, if clicked that it shows the second textview (Text), and if clicked again that it hides it. When I use an onClick ( android:onClick="ClText" ) I get an error. I think I should use something of an onClickListener , but since I'm new to Android I'm not quite sure how to use it. Can someone help me out with the code please? You just need to set the onClickListener for the first item in the

I want to set OnClickListener on the ImageViews after I make them using addView method dynamically and rotate them in my application. But onClick method doesn't work properly when I pressed ImageView on screen. If I press the screen at the original location of the ImageView, it works. I want to make other ImageViews in advanced at the final location after rotation animation, but I don't know how to make ImageView having skewed Layout. I'm waiting for your help..... Thank you. import android.app.Activity; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android

体验DOM操作 1. <!--html代码--> <input type="button" value="弹框" onclick="alert('哈哈，我又变漂亮了')" /> 2. <input type="button" value="显示效果" id="btn" /> <script> document.getElementById("btn").onclick = function () { alert("哈哈，我又变漂亮了"); }; </script> 来源： https://www.cnblogs.com/jane-panyiyun/p/11981451.html

I was asked to refactor the getView() code presented below. I have got ListView with custom Adapter. Every row contains clickable buttons and texts. At the moment onClickListeners are set in the body of getView() , this is quite insane idea, because this method is called very frequently. Inside of every onClick function I need access to the private data to call new activity with bundle. How can i move onClick definition outside getView() routine? When onClick will be called I need info about position of list element (to access private data) and which View was clicked (to start correct Activity

Often I have maps with a whole lot of markers (let's say representing shops). I have infowindows that display basic info on the shop represented by the marker, then, on the infoWindow HTML I like to put a button that, for example, says "Details". The html of the infowindow is simple.. the html of the info window would include an input type="button" value="Show More" onclick="showMore(' + shopId + '); The relevant shopId would be obviously different for every marker... The problem is that the showMore function has to be declared as a global function to the javascript otherwise the infowindow

Is there any way I can capture a name of an item clicked in a list view when using "onItemLongClickListiner" ? I know I can capture position etc but I need a name I suppose that you ListView is filled up with String object: public boolean onItemLongClick (AdapterView<?> parent, View view, int position, long id) { String name = (String) parent.getItemAtPosition(position); } AdapterView.getItemAtPosition(position) gets the data associated with the specified position in the list. You can use lv.getItemAtPosition(position) to get the text based on the index position lv.setOnItemClickListener(new

return false最简单的理解就是取消“浏览器默认行为”。 比如一个链接 百度知道 ，当我们点击这个链接时，浏览器会自动跳转到：zhidao.baidu.com这个地址，这是浏览器的默认行为。但如果我们这么做： 百度知道 那么再次点击这个链接时，浏览器则不会进行跳转。 js在事件中调用函数时用return返回值实际上是对window.event.returnvalue进行设置。而该值决定了当前操作是否继续。当返回的是true时，将继续操作。当返回是false时，将中断操作。而直接执行时（不用return），将不会对window.event.returnvalue进行设置,所以会默认地继续执行操作。 例如： （1） Open ，如果函数 add_onclick() 返回 true, 那么 页面就会打开 abc.htm否则, (返回 false), 那么页面不会跳转到 abc.htm, 只会执行你的 add_onclick() 函数里的内容. (add_onclick函数中控制页面转到 abc.htm除外 （2） ，submitAction()方法里面有提交表单的动作。万一不加 return false，因为输入类型为提交按钮，在执行完 submitAction 方法后，submit 按钮还会继续执行它的默认事件（提交表单），加上return false后

JAVASCRIPT在事件中调用函数时用return返回值实际上是对window.event.returnvalue进行设置。 而该值决定了当前操作是否继续。 当返回的是true时，将继续操作。 当返回是false时，将中断操作。 而直接执行时（不用return）。将不会对window.event.returnvalue进行设置 所以会默认地继续执行操作 详细说明如下： 例如： 当在 <a href="abc.htm" οnclick="return add_onclick()">Open</a> 中 如果函数 add_onclick() 返回 true, 那么 页面就会打开 abc.htm 否则, (返回 false), 那么页面不会跳转到 abc.htm, 只会执行你的 add_onclick() 函数里的内容. (add_onclick函数中控制页面转到 abc.htm除外 ) 而 <a href="abc.htm" οnclick="add_onclick()">Open</a> 不管 add_onclick() 返回什么值, 都会在执行完 add_onclick 后打开页面 abc.htm 另外补充： onclick事件时就相当于οnclick="return true/false" 例： function check() { if(obj.value=="" ) {
