TableLayout Visibility GONE仅在第二次单击按钮时起作用

标签: android button visibility tablelayout

我遇到TableLayout问题。当我点击“清除”按钮时,我试图隐藏其所有内容。但是,只有当我在按钮上单击两次时它才有效。我还有两个单选按钮隐藏或显示此表格布局。奇怪的是,当单击具有完全相同代码的单选按钮时,它正在工作:setVisibility(View.GONE)setVisibility(View.VISIBLE)

如果你能帮助我,那就太棒了。

以下是代码:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.dialog_task_validation);

        setTitle("Task Validation");

        // set the custom dialog components - text, image and button
        final RadioGroup radioGroupTask = (RadioGroup) findViewById(R.id.radioGroup);
        radioGroupTask.clearCheck();

        noteLayout = (TableLayout) findViewById(R.id.noteLayout);


        radioGroupTask.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) {
                RadioButton rb = (RadioButton) group.findViewById(checkedId);
                if (rb != null && checkedId > -1) {
                    switch (checkedId) {
                        // If task Failed
                        case R.id.taskFailedRadioButton:
                            taskCompeleted = 0;
                            noteLayout.setVisibility(View.GONE);
                            note = 0;
                            break;
                        case R.id.taskCompletedRadioButton:
                            taskCompeleted = 1;
                            noteLayout.setVisibility(View.VISIBLE);
                            break;
                    }
                }

            }
        });
        Button clear = (Button) findViewById(R.id.clearDialogButton);


        clear.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                noteLayout.setVisibility(View.GONE);
                resetButtonBackground();
                note = -1;
                taskCompeleted = -1;
                radioGroupTask.clearCheck();
            }
        });
    }

只是为了帮助其他人,我将在此报告我的评论:

删除clearCheck 中的button click listener来电(或在更改可见性之前将其移动),因为它会触发onCheckedChange radioGroupTask听众},这将再次更改您的layout

clearCheck() - 清除选择。首先,您需要清除选择。首先需要隐藏TableLayout。
