所以我想打電話給onFinish與outComeButton:呼叫onFinish的按鈕外定時器

import java.util.concurrent.TimeUnit; 
import android.app.Activity; 
import android.content.Context; 
import android.os.Bundle; 
import android.os.CountDownTimer; 
import android.os.Vibrator; 
import android.view.Menu; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.inputmethod.InputMethodManager; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.TextView; 

public class OutCome0 extends Activity { 
    private CountDownTimer countDownTimer; 
    private boolean timerHasStarted = false; 
    public TextView text; 
    private final long interval = 1 * 1000; 
    EditText editTime1; 
    Button startButton; 

    /*Skip go straight to an outcome 
    * To Do Instead of having two sets of the same shit, call onFinish here.*/ 
     public void outComeButton(View v){ 
      ; 
     }; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_out_come0); 
     editTime1 = (EditText)findViewById(R.id.editTime1);  
     startButton = (Button)findViewById(R.id.startButton); 
     text = (TextView) this.findViewById(R.id.timer); 
     startButton.setOnClickListener(new OnClickListener() { 

      /*Start the timer */ 
      public void onClick(View v) { 
       // get the name from edittext and storing into string variable 
       long timeVal = Long.parseLong(editTime1.getText().toString()); 
       /* the keyboard wasen't auto hiding. below three lines force it closed.*/ 
       InputMethodManager imm = (InputMethodManager)getSystemService(
          Context.INPUT_METHOD_SERVICE); 
        imm.hideSoftInputFromWindow(startButton.getWindowToken(), 0); 

       if (!timerHasStarted) { 
        countDownTimer = new MyCountDownTimer(timeVal * 1000 * 60, interval); 
        text.setText(text.getText() + String.valueOf(timeVal/1000)); 
        countDownTimer.start(); 
        timerHasStarted = true; 
        startButton.setText("STOP"); 
       } else { 
        countDownTimer.cancel(); 
        timerHasStarted = false; 
        startButton.setText("RESTART"); 
       } 
      } 
      class MyCountDownTimer extends CountDownTimer { 
       public MyCountDownTimer(long timeVal, long interval) { 
       super(timeVal, interval); 
       } 

      public void outComeButton(View v){ 
       this.onFinish(); 
      }; 
       /* Converts tick time to 00:00 need to fix so that 1 min 30 seconds is 01:30 instead of 01:3 
       * Currently hidden, maybe though do somthing with onTick later.*/    
       @Override 
       public void onTick(long millisUntilFinished) { 
       /* text.setText(""+String.format("%d:%d", 
         TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished), 
         TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) - 
         TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished)) 
        ));*/ 
       } 

       @Override 
       /* Finish event Need to make it so that videos can be played if solo mode.*/ 
       public void onFinish() { 
        int num; 
        String outCome = ""; 
        for (int ii = 0; ii < 10; ii++) { 
         num = (int) (Math.random() * 100) % 4; 

         switch (num) { 
         case 0: 
         case 1: 
          outCome = "Outcome1"; 
          break; 
         case 2: 
          outCome = "outcome2"; 
          break; 
         case 3: 
          outCome = "outcome3"; 
          break; 
       } 
        text.setText(outCome); 
      } 
       Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); 
       // Vibrate for 5 seconds 
       v.vibrate(5000); 
       } 
      } 
      }); 
    } 
    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.out_come0, menu); 
     return true; 
    } 

} 

它抱怨說outComeButton從未在本地使用的方法。我的XML有沒有問題,或者我把按鈕放在了錯誤的地方?

<Button 
     android:id="@+id/outComeButton" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:onClick="outComeButton" 
     android:text="@string/outComeButton" /> 

而且錯誤,我從logcat中獲得當我嘗試按下按鈕:

如果您在佈局XML文件中使用'android:onClick'指定偵聽器,則該方法(在代碼中)必須包含一個包含'View'作爲參數的簽名,例如'public void outComeButton(View v)' 。 – Squonk

我編輯它,我得到同樣的問題... – cflinspach

你的'outComeButton'的定義是在同一個XML佈局文件中,由你定義方法的'Activity'使用?正確? – Squonk

中的onClick你指着XML佈局文件必須是已膨脹的活動的一部分查看與按鈕。

將方法提取出來並從那裏完成計時器,並且一切都應該正常工作。

一般來說,在XML中聲明onClick是不好的做法,應該避免。

「從來沒有使用過本地」的警告來自內部類的匿名OnClickListener第二個outComeButton()方法。

用XML定義onClick偵聽器需要在活動中找到它。如果您刪除或註釋掉了第一個活動級別outComeButton()方法,這將解釋堆棧跟蹤中的異常。

刪除內部outComeButton(),並在活動級別的方法中執行您想完成的操作。
