Android中AlertDialog為一些程序提供了對話框，有些功能能夠進一步滿足程序的需要。下面舉例介紹。
程序如下：
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class A01Activity extends Activity {
Button b;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
b=(Button)findViewById(R.id.button);
b.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new AlertDialog.Builder(A01Activity.this)
.setTitle(R.string.str_title)
.setIcon(R.drawable.fei)
.setMessage(R.string.str_message)
.setPositiveButton("OK",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
finish(); //結束該程序的Activity
}
})
//返回該程序的Activity
.setNegativeButton("NO", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
}).show();
}
});
}
}
