以上是新建一個class文件，最關鍵的自定義代碼，以下就是在activity之中直接調用即可，中間用到的圖片什么的，自己選好添加即可，

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

final AlertDialog ad = new AlertDialog(MainActivity.this);

ad.setTitle("標題");

ad.setMessage("內容sdfs容內容內容內容內容內容內容");

ad.setPositiveButton("確定", new OnClickListener() {

@Override

public void onClick(View v) {

ad.dismiss();

Toast.makeText(MainActivity.this, "被點到確定", Toast.LENGTH_LONG)

.show();

}

});

ad.setNegativeButton("取消", new OnClickListener() {

@Override

public void onClick(View v) {

ad.dismiss();

Toast.makeText(MainActivity.this, "被點到取消", Toast.LENGTH_LONG)

.show();

}

});

}

}
