代碼裡面:
<PRE class=java name="code">private void CreateLoginAlert()
{
LayoutInflater factory = LayoutInflater.from(LoginActivity.this);
//得到自定義對話框
View DialogView = factory.inflate(R.layout.login_dialog, null);
AlertDialog.Builder ad =new AlertDialog.Builder(this);
ad.setTitle("賬號登陸");
ad.setView(DialogView);
adi= ad.create();
adi.setButton("登錄", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
username = (EditText)adi.findViewById(R.id.txt_username);

loginerror = (TextView)adi.findViewById(R.id.txt_loginerror);
m_Dilog=ProgressDialog.show(LoginActivity.this, "請等待...", "正在為你登陸...",true);
mRedrawHandler.sleep(100);
}
});
adi.setButton2("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

});
adi.show();
}
private RefreshHandler mRedrawHandler = new RefreshHandler();

} catch (Exception e) {

}
if(username.getText().length() == 0)
{

} catch (IOException e) {

}
super.handleMessage(msg);
}
}
public void sleep(long delayMillis)
{

}
}
就這麼簡單,效果圖如下:
