我有ContactUs.java和Mail.java课。
我想将方法从 Mail 类调用到Contactus onclicklistner方法中。
package com.hesham.sams;
public class ContactusActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contactus);
TextView subjectTxt = (TextView) findViewById(R.id.subjectTxt);
TextView emailTxtus = (TextView) findViewById(R.id.emailTxtus);
final TextView messageTxt = (TextView) findViewById(R.id.messageTxt);
Button lButton = (Button)findViewById(R.id.sendbtn);
String hh = messageTxt.getText().toString();
Spinner s = (Spinner) findViewById(R.id.spinner1);
Typeface font = Typeface.createFromAsset(getAssets(), "extrafine.ttf");
subjectTxt.setTypeface(font);
emailTxtus.setTypeface(font);
messageTxt.setTypeface(font);
String array_spinner[];
array_spinner=new String[3];
array_spinner[0]="general";
array_spinner[1]="quisiton";
array_spinner[2]="suggsution";
Spinner spinner = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, array_spinner);
spinnerArrayAdapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );
spinner = (Spinner) findViewById( R.id.spinner1 );
spinner.setAdapter(spinnerArrayAdapter);
//ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_spinner_dropdown_item, array_spinner);
//adapter.setDropDownViewResource(R.layout.special_spinner_dropdown);
//s.setAdapter(adapter);
// send Botton
//public string hesham(){
lButton.setOnClickListener(
new View.OnClickListener()
{
public void onClick(View view)
{
// here is the proeblem
Mail.send();
}
});
// ignoring
final class SpinnerActivity implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// An item was selected. You can retrieve the selected item using
// parent.getItemAtPosition(pos)
Spinner spinner = (Spinner) findViewById(R.id.spinner1);
spinner.setOnItemSelectedListener(this);
}
public void onNothingSelected(AdapterView<?> parent) {
// Another interface callback
}
}
}// end of on create
} // end of class
二等：

注意：我不能使用extend，因为这个类中的每一个都已经捍卫到扩展另一个类。你知道java不能同时扩展两个类吗？
