原因是
mDigits.setKeyListener(DialerKeyListener.getInstance()); mDigits.setInputType(InputType.TYPE_CLASS_PHONE);
把这两行去掉并加上一句mDigits.setInputType(InputType.TYPE_NULL);就行了！
Phone那个拨号界面对应的是Contacts下的TwelveKeyDialer.java
本身采用的是
playTone(ToneGenerator.TONE_DTMF_1);//生音是否显示 keyPressed(KeyEvent.KEYCODE_1);//输入的数字
mHaptic.vibrate();//震动 KeyEvent event = new KeyEvent(KeyEvent.ACTION_DOWN, keyCode); mDigits.onKeyDown(keyCode, event);//keycode对应的就是KeyEvent.KEYCODE_1
keyCode对应的去取对应的值！这个值对应的在MultiTapKeyListener.java中有定义！
static {
sRecs.put(KeyEvent.KEYCODE_1, ".,1!@#$%^&*:/?'=()");
sRecs.put(KeyEvent.KEYCODE_2, "abc2ABC");
sRecs.put(KeyEvent.KEYCODE_3, "def3DEF");
sRecs.put(KeyEvent.KEYCODE_4, "ghi4GHI");
sRecs.put(KeyEvent.KEYCODE_5, "jkl5JKL");
sRecs.put(KeyEvent.KEYCODE_6, "mno6MNO");
sRecs.put(KeyEvent.KEYCODE_7, "pqrs7PQRS");
sRecs.put(KeyEvent.KEYCODE_8, "tuv8TUV");
sRecs.put(KeyEvent.KEYCODE_9, "wxyz9WXYZ");
sRecs.put(KeyEvent.KEYCODE_0, "0+");
sRecs.put(KeyEvent.KEYCODE_POUND, " ");
};
根据这个MultiTapKeyListener.java的注释
/** * This is the standard key listener for alphabetic input on 12-key * keyboards. You should generally not need to instantiate this yourself; * TextKeyListener will do it for you. */
说明实际是由TextKeyListener.java来控制的！
@Override
public boolean onKeyDown(View view, Editable content,
int keyCode, KeyEvent event) {
KeyListener im = getKeyListener(event);
return im.onKeyDown(view, content, keyCode, event);
}
KeyListener 接口对应的返回实例在这里类型有两种！
private KeyListener getKeyListener(KeyEvent event) {
KeyCharacterMap kmap = KeyCharacterMap.load(event.getKeyboardDevice());
int kind = kmap.getKeyboardType();
if (kind == KeyCharacterMap.ALPHA) {
return QwertyKeyListener.getInstance(mAutoText, mAutoCap);
} else if (kind == KeyCharacterMap.NUMERIC) {
return MultiTapKeyListener.getInstance(mAutoText, mAutoCap);
}
return NullKeyListener.getInstance();
}
/**
* Returns {@link #NUMERIC}, {@link #PREDICTIVE} or {@link #ALPHA}.
*/
public int getKeyboardType()
{
return getKeyboardType_native(mPointer);
}
private static native int getKeyboardType_native(int ptr);返回NUMERIC数值类型或ALPHA希腊字母类型或PREDICTIVE这个返回的实际就是空的类型.
最后这个值是怎么取出来的列！已返回QwertyKeyListener.getInstance(mAutoText, mAutoCap);为例。
在QwertyKeyListener的onKeyDown方法中的
int i = event.getUnicodeChar(getMetaState(content));
public int getUnicodeChar(int meta) {
return KeyCharacterMap.load(mDeviceId).get(mKeyCode, meta);
}
private static native char get_native(int ptr, int keycode,
int meta);
键布局映射文件通常放在/system/usr/keylayout和/data/usr/keylayout
对于每一个键盘设备xxx,设置系统属性android.keylayout.xxx,如果没有为自己的硬件设备创建一个特定的设备，Android将去读/system/usr/keylayout/qwerty.kl这个配置文件。
