Question

我有RelativeLayout saveCancelBar，其中包含RelativeLayouts中也包含的两个按钮。只有点击saveCancelBar EditText或焦点时才会显示pageTitle。出于某种原因，当我单击任何按钮时没有任何反应，并且当onClick事件（显示Toast，隐藏软键盘并隐藏EditText光标）时不会触发我点击它们。

我所指的按钮是＆＃34;取消＆＃34;和＆＃34;保存标题＆＃34;而saveCancelBar是包含两者的布局。我确实设置了android:clickable="true"。这是活动的XML代码：

具体来说，这些是我的onClick侦听器：

saveButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if(!TextUtils.isEmpty(pageTitle.getText().toString())) {
            pageTitle.clearFocus();
            getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_HIDDEN);
            saveCancelBar.clearAnimation();
            saveCancelBar.setVisibility(View.GONE);
            Toast.makeText(AddPhotoActivity.this, "Title is successfully saved", Toast.LENGTH_SHORT).show();

        } else {
            Toast.makeText(AddPhotoActivity.this, "Title is too short.", Toast.LENGTH_SHORT).show();
        }
    }

});

cancelButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        pageTitle.clearFocus();
        getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_HIDDEN);
        saveCancelBar.clearAnimation();
        saveCancelBar.setVisibility(View.GONE);
    }
});

编辑：我修改了saveButton＆＃39; onClickListener的if条件，并根据@Nilesh和@ Exigente05的建议将.show()方法添加到祝酒词中。我还添加了pageTitle.clearFocus()。对代码的更新设法显示祝酒词并隐藏EditText光标，但saveCancelBar和软键盘仍然存在。

Answer 1

使用此

if(!TextUtils.isEmpty(pageTitle.getText().toString())) {
       getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_HIDDEN);
       saveCancelBar.setVisibility(View.GONE);
        Toast.makeText(AddPhotoActivity.this, "Title is successfully saved", Toast.LENGTH_SHORT).show();

 } else {
        Toast.makeText(AddPhotoActivity.this, "Title is too Short.", Toast.LENGTH_SHORT).show();
 }

而不是

if(pageTitle.getText() != null) {
       getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_HIDDEN);
       saveCancelBar.setVisibility(View.GONE);
       Toast.makeText(AddPhotoActivity.this, "Title is successfully saved", Toast.LENGTH_SHORT);

} else {
       Toast.makeText(AddPhotoActivity.this, "Title is too short.", Toast.LENGTH_SHORT);
 }

Answer 2

if(pageTitle.getText() != null)

你检查过这种情况吗？

Answer 3

我将回答最有趣的发现。

你知道吗？

一切正常，只需要在两个特定的Toast.makeText的末尾添加.show()。请仔细查看，在第220和223行，您忘了拨打.show()

这不好笑吗？

另一件事pageTitle.getText() != null永远都是真的。您需要检查文本长度或emptyText以获得准确的结果。

在saveButton.setOnClickListener

中隐藏键盘和清除焦点更改代码

    saveButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if(pageTitle.getText() != null) {
//              pageTitle.clearFocus();
                View view = ClassName.this.getCurrentFocus();
                if (view != null) {
                    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
                }
                pageTitle.clearFocus();
                saveCancelBar.clearAnimation();
                saveCancelBar.setVisibility(View.GONE);
                Toast.makeText(MainActivity.this, "Title is successfully saved", Toast.LENGTH_SHORT).show();

            } else {
                Toast.makeText(getApplicationContext(), "Title is too short.", Toast.LENGTH_SHORT).show();
            }
        }

    });

同样在cancelButton.setOnClickListener

中加入相同的机制

无法点击RelativeLayout上的按钮
