//在dialog show方法之前添加如下代碼说榆，表示該dialog是一個系統(tǒng)的dialog
dialog.getWindow().setType((WindowManager.LayoutParams.TYPE_SYSTEM_ALERT));

Builder builder = new AlertDialog.Builder(this);
builder.setTitle("提示");
builder.setMessage("在service中打開的dialog");
builder.setNegativeButton("取消", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.setPositiveButton("確定", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
final AlertDialog dialog = builder.create();

new Thread(){

SystemClock.sleep(4000);
hanlder.post(new Runnable() {
@Override
public void run() {
dialog.show();
}
});
};
