您可以使用onKeyDown方法

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if(keyCode ==KeyEvent.KEYCODE_0){

        // note this if called
    }else if(keyCode ==KeyEvent.KEYCODE_1){
    // note this if called  
    }else if(keyCode ==KeyEvent.KEYCODE_2){
    // note this if called  
    }else if(keyCode ==KeyEvent.KEYCODE_3){
    // note this if called  
    }elseif(keyCode ==KeyEvent.KEYCODE_4){
    // note this if called  
    }else....
        .....
    return super.onKeyDown(keyCode, event);
}
