如何跟踪Android中软键盘上按下的键？

Question

How can I track the keys pressed by the user in keyboard in android? Is this possible or I have to create a keyboard myself? What could be the possible way ?

Answer 1

Please check Creating An Input Method . This would help you in creating a custom Input Method. You can check the Sample Application in your Android SDK directory. Please follow as per this link .

Answer 2

One way to liste for those is:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        // Log the Key that was pressed or do whatever you need
        // keyCode contains all the possible keyCode presses
    }
    else if(keyCode == KeyEvent.KEYCODE_1){
        //You can insert catches for each particular keypress here
    }
    return super.onKeyDown(keyCode, event);
}
