Android App监听软键盘按键的三种方式与改变软键盘右下角确定键样式

actionNone : 回车键，按下后光标到下一行
actionGo ： Go，
actionSearch ： 放大镜
actionSend ： Send
actionNext ： Next
actionDone ： Done，确定/完成，隐藏软键盘，即使不是最后一个文本输入框

android:singleline="true"

android:imeoptions="actionSearch"

EditText.setOnEditorActionListener设置监听

 @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        boolean isOK = true;
        switch (actionId) {
            case EditorInfo.IME_ACTION_NONE:
                Toast.makeText(mContext, "点击-->NONE", Toast.LENGTH_SHORT).show();
                break;
            case EditorInfo.IME_ACTION_GO:
                Toast.makeText(mContext, "点击-->GO", Toast.LENGTH_SHORT).show();
                break;
            case EditorInfo.IME_ACTION_SEARCH:
                Toast.makeText(mContext, "点击-->SEARCH", Toast.LENGTH_SHORT).show();
                break;
            case EditorInfo.IME_ACTION_SEND:
                Toast.makeText(mContext, "点击-->SEND", Toast.LENGTH_SHORT).show();
                break;
            case EditorInfo.IME_ACTION_NEXT:
                Toast.makeText(mContext, "点击-->NEXT", Toast.LENGTH_SHORT).show();
                break;
            default:
                isOK = false;
                break;
        }
