setOnTouchListener() is giving me an error
提问by Si8
button.setOnTouchListener(new OnTouchListener()
{
public void onClick(View v)
{
Toast.makeText(MainActivity.this, "YOUR TEXT", 5000).show();
}
});
Eclipse states the following:
Eclipse 声明如下：
The method setOnTouchListener(View.OnTouchListener) in the type View is not applicable for the arguments (new OnTouchListener(){})
类型View中的setOnTouchListener(View.OnTouchListener)方法不适用于参数(new OnTouchListener(){})

There are two solutions:
有两种解决方案：
Add
import android.view.View.OnTouchListener;to the beginning of your classReplace
button.setOnTouchListener(new OnTouchListener()withbutton.setOnTouchListener(new ViewOnTouchListener()as Chiral Code suggested.
添加
import android.view.View.OnTouchListener;到班级开头更换
button.setOnTouchListener(new OnTouchListener()与button.setOnTouchListener(new ViewOnTouchListener()手性代码建议。

Check your code: http://developer.android.com/reference/android/view/View.OnTouchListener.htmlYou should use method onTouch.
检查您的代码：http://developer.android.com/reference/android/view/View.OnTouchListener.html您应该使用 onTouch 方法。

The code
编码
public void onClick(View v)
{
Toast.makeText(MainActivity.this, "YOUR TEXT", 5000).show();
}
is not valid for an onTouchListener. That is why you are getting the error, you should be using
对 onTouchListener 无效。这就是为什么你收到错误，你应该使用
@Override
public void onTouch(View v, MotionEvent e)
{
Toast.makeText(MainActivity.this, "YOUR TEXT", 5000).show();
}
instead if you really want an onTouchListener, although I highly suggest Chiral Code's suggestion of using an onClickListener
相反，如果你真的想要一个 onTouchListener，虽然我强烈建议手性代码建议使用 onClickListener
回答by Srikanth Roopa
and when u use new OnTouchListener() u need to override on onTouch not onClick or change it to
plus.setOnClickListener(new OnClickListener()
当您使用 new OnTouchListener() 时，您需要覆盖 onTouch 而不是 onClick 或将其更改为
plus.setOnClickListener(new OnClickListener()
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "YOUR TEXT", 5000).show();
return false;
}
回答by amruzzzzzzzzzi
you are putting an ontouchlistener with an onclick listener thats your mistake.
您将 ontouchlistener 与 onclick 侦听器放在一起，那是您的错误。
button.setOnTouchListener(new OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(MainActivity.this, "YOUR TEXT", 5000).show();
return false;
}
});

I also had this problem and I had to do 'fix project setup' which I found after clicking the quick fixes option. I then added a .jar file and it was all good.
我也遇到了这个问题，我必须执行“修复项目设置”，这是我在单击快速修复选项后发现的。然后我添加了一个 .jar 文件，一切都很好。
