Java Android - setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (new OnClickListener(){})
提问by Thomas VC
When using the following code i keep getting errors, i know there is another way of using the onclick functions, android:onclick... but i prefer this 'cleaner' way.
使用以下代码时，我不断收到错误消息，我知道还有另一种使用 onclick 函数的方法，android:onclick...但我更喜欢这种“更干净”的方式。
the id name of the textview is right but i keep getting this error with the onclicklistener.
textview 的 id 名称是正确的，但我一直在使用 onclicklistener 收到此错误。
what am i doing wrong?
我究竟做错了什么？
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
TextView text = (TextView) findViewById(usernameText);
text.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// Do some job here
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_screen, menu);
return true;
}`

The problem may be a jar that you imported that has an onClickListener...
问题可能是您导入的 jar 具有 onClickListener ...
Try add this:
尝试添加这个：
text.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
// Do some job here
}
});

without seeing your error, I'd guess that you probably imported the wrong OnClickListener. Make sure that it's the View one.
没有看到您的错误，我猜您可能导入了错误的 OnClickListener。确保它是视图之一。
