我尝试将该方法实现到我的Button onClickListener
中,然后我得到了Syntax Error
。
以下是我的代码:
// button click event
btnCreateNewEvent.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
// Checking for server respond
if (serverRespond() == false) {
//DO SOMETHING
}
以下是ServerRespond
方法
onCreate
// Check server respond
public boolean serverRespond() {
boolean success = false;
try {
URL url = new URL(url_create_event);
HttpURLConnection urlcon = (HttpURLConnection) url.openConnection();
urlcon.connect();
if (urlcon.getResponseCode() == 200) {
success = true;
}
} catch (Exception e) {
Log.e(create_error.toString(), "Server is not responding");
}
return success;
}
错误:在if(serverRespond()==true){
"The method serverRespond() is undefined for the type new View.OnClickListener(){}"

您可以通过以下方式访问:
YourActivity.this.serverRespond()
答案 1 :(得分:1)
我认为你是按照以下方式调用serverRespond()方法:
this.serverRespond();
并且由于此方法在实现OnClickListener的类中,它将在此类或OnClickListener中搜索此方法。将其更改为:
serverRespond();
或
YourActivity.this.serverRespond()

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button btn = (Button) findViewById(R.id.btn);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (serverRespond() == false) {
Toast.makeText(getApplicationContext(), "onClick",
Toast.LENGTH_LONG).show();
}
}
});
}
public boolean serverRespond() {
Toast.makeText(getApplicationContext(), "serverRespond",
Toast.LENGTH_LONG).show();
return false;
}
