我是Android开发的新手,我想知道如何链接一个对话框(里面有一个选项列表),当按下UI上的按钮时,对话框应该打开
到目前为止我写的代码:
package awad865.project.ContactManager1;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
public class OptionActivity extends Activity {
private Button button1;
private Button button2;
private Button button3;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_option);
getActionBar().setDisplayShowTitleEnabled(false);
getActionBar().setDisplayShowHomeEnabled(false);
button1=(Button) findViewById(R.id.button_sort);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
AlertDialog.Builder builder = new AlertDialog.Builder(OptionActivity.this);
builder.setTitle("Sort list by?");
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.option, menu);
return true;
}
}
