Question

我有自定义键盘带红色按钮当我按下例如数字1时颜色变为蓝色当我从屏幕拉动手指回到红色时，我想保持蓝色任何人都知道怎么做这里的我的颜色变化（按下）xml

  <selector xmlns:android="http://schemas.android.com/apk/res/android"
      >
           <item
      android:state_pressed="true"
       android:drawable="@drawable/pressed" />

   <item
    android:state_checkable="true"
    android:state_pressed="true"
    android:drawable="@drawable/download" />


 <item android:drawable="@drawable/red"/>



           </selector>

检查一下：

public class BasicOnKeyboardActionListener implements KeyboardView.OnKeyboardActionListener {

private Activity mTargetActivity;



public BasicOnKeyboardActionListener(Activity targetActivity) {



    mTargetActivity = targetActivity;
}

@Override
public void swipeUp() {
    // TODO Auto-generated method stub

}

@Override
public void swipeRight() {
    // TODO Auto-generated method stub

}

@Override
public void swipeLeft() {
    // TODO Auto-generated method stub

}

@Override
public void swipeDown() {
    // TODO Auto-generated method stub

}

@Override
public void onText(CharSequence text) {
    // TODO Auto-generated method stub

}

@Override
public void onRelease(int primaryCode) {

    }

    // TODO Auto-generated method stub


  @Override
  public void onPress(int primaryCode) {

    }

    // TODO Auto-generated method stub

  @Override
  public void onKey(int primaryCode, int[] keyCodes)

{

    long eventTime = System.currentTimeMillis();
    KeyEvent event = new KeyEvent(eventTime, eventTime,
            KeyEvent.ACTION_DOWN, primaryCode, 0,  0 ,0 , 0,
            KeyEvent.FLAG_SOFT_KEYBOARD | KeyEvent.FLAG_KEEP_TOUCH_MODE);

Add this methods to the `keyboardListner`

 public class SimpleIME extends InputMethodService
    implements OnKeyboardActionListener{

    private KeyboardView kv;
    private Keyboard keyboard;

    private boolean caps = false;

    @Override
    public void onKey(int primaryCode, int[] keyCodes) {        

    }

    @Override
    public void onPress(int primaryCode) {
    }

    @Override
    public void onRelease(int primaryCode) {            
    }

    @Override
    public void onText(CharSequence text) {     
    }

    @Override
    public void swipeDown() {   
    }

    @Override
    public void swipeLeft() {
    }

    @Override
    public void swipeRight() {
    }

    @Override
    public void swipeUp() {
    }
}

并更改onpressed和OnReleased颜色
