本文实例讲述了Android创建Alert框的方法。分享给大家供大家参考。具体如下：
package com.akwolf.android;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class DialogActivity extends Activity {
/** Called when the activity is first created. */
Button dialogBtn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
dialogBtn = (Button) findViewById(R.id.button1);
dialogBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
new AlertDialog.Builder(DialogActivity.this)
.setIcon(R.drawable.icon).setTitle("Infomation")
.setMessage("Hello World").show();
}
});
}
}
希望本文所述对大家的Android程序设计有所帮助。
