因為我們只要測試是否連線正常   回傳 200 為正常
只要有產生 php 的檔案就可以了!!

一個.java檔 完成呼叫google語音辨識系統

Android App 控制返回鍵

因為返回件為大多數Android 手機必備的按鍵

在我昨天學到的三秒跳轉頁面發現這樣一個問題

按下回上一頁@@

怎麼跳回去上一個activity的頁面了!!

今天研究出了解決這樣的問題點

@Override
public void run() {
// TODO Auto-generated method stub
try {
Thread.sleep(3000);
startActivity(new Intent().setClass(SplashActivity.this, MainActivity.class));
/*如果要在三秒後跳到主頁面後返回不要跳回此頁，可加入這行*/
     xsystarActivity.this.finish(); 
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}).start();
}


加上一點美感的返回對話框


protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
   
    /*返回建設定*/
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if ((keyCode == KeyEvent.KEYCODE_BACK)) {  

            ConfirmExit();

            return true;

        }

        return super.onKeyDown(keyCode, event);

}
   
    private void ConfirmExit() {
// TODO Auto-generated method stub
    AlertDialog.Builder ad=new AlertDialog.Builder(MainActivity.this); //創建訊息方塊

        ad.setTitle("離開");

        ad.setMessage("確定要離開?");

        ad.setPositiveButton("是", new DialogInterface.OnClickListener() { //按"是",則退出應用程式

            public void onClick(DialogInterface dialog, int i) {

              MainActivity.this.finish();

       }

     });

        ad.setNegativeButton("否",new DialogInterface.OnClickListener() { //按"否",則不執行任何操作

            public void onClick(DialogInterface dialog, int i) {

       }

語音文字判斷(比對)

最近在用語音出來的文字如何判斷

今天終於給我是出來了


List<String> list = it.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);      
     
 /*這段再作判斷以及取得list取得第一個陣列文字作判斷就好了*/
       if (list.get(0).equals("賽夏")) {
        tv.setText("賽夏");
       }else {
        tv.setText("查無此意");
       }

語音請參考這裡：http://kuoapp.blogspot.tw/2014/11/android.html
