I'm working on a little personal todo list app and so far everything has been working quite well. There is one little quirk I'd like to figure out. Whenever I go to add a new item, I have a Dialog with an EditText view showing inside. When I select the EditText view, the keyboard comes up to enter text, as it should. In most applications, the default seems to be that the shift key is held for the first letter... although it does not do this for my view. There has to be a simple way to fix, but I've searched the reference repeatedly and cannot find it. I'm thinking there has to be an xml attribute for the reference loaded by the Adapter, but I can't find out what it is.

我也遇到了同样的问题,只是分享了我的发现。可能会帮助你和其他人…

在你的布局上试试这个。在EditText中添加下面的行。

android:inputType="textCapWords|textCapSentences"

对我来说很好..希望它也适用于你…

试试这个代码,它将大写所有单词的第一个字符。

-为EditText视图设置addTextChangedListener

edt_text.addTextChangedListener(观察者);

-添加文本观察者

TextWatcher watcher = new TextWatcher() {
    int mStart = 0;

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        mStart = start + count;
    }

    @Override
    public void afterTextChanged(Editable s) {
        String input = s.toString();
        String capitalizedText;
        if (input.length() < 1)
            capitalizedText = input;
        else if (input.length() > 1 && input.contains(" ")) {
            String fstr = input.substring(0, input.lastIndexOf(" ") + 1);
            if (fstr.length() == input.length()) {
                capitalizedText = fstr;
            } else {
                String sstr = input.substring(input.lastIndexOf(" ") + 1);
                sstr = sstr.substring(0, 1).toUpperCase() + sstr.substring(1);
                capitalizedText = fstr + sstr;
            }
        } else
            capitalizedText = input.substring(0, 1).toUpperCase() + input.substring(1);

        if (!capitalizedText.equals(edt_text.getText().toString())) {
            edt_text.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                }

                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {

                }

                @Override
                public void afterTextChanged(Editable s) {
                    edt_text.setSelection(mStart);
                    edt_text.removeTextChangedListener(this);
                }
            });
            edt_text.setText(capitalizedText);
        }
    }
};

只需在EditText元素中使用android:inputType="textCapWords"即可。

例如:

<EditText
    android:id="@+id/txtName"
    android:layout_width="0dp"
    android:layout_height="40dp"
    android:layout_weight="0.7"
    android:inputType="textCapWords"
    android:textColorHint="#aaa"
    android:hint="Name Surname"
    android:textSize="12sp" />

请参考以下链接: http://developer.android.com/reference/android/widget/TextView.html#attr_android%3ainputType

静态地(即在你的布局XML文件):设置android:inputType=" textcapsentence "在你的EditText。

编程上:你必须包括InputType。在EditText的InputType中的TYPE_CLASS_TEXT,例如

EditText editor = new EditText(this); 
editor.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_CAP_SENTENCES);

可以与文本及其变体相结合,以要求每个句子的第一个字符大写。

-谷歌文档

如果你想在每个单词的首字母大写,然后使用android:inputType="textCapWords"

为了更好地理解

 <EditText
    android:id="@+id/edt_description"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textCapWords"/>

如果你每个句子都用大写的单词,那就用它。 android:inputType=" textcapsentence "这一行在你的xml。我指的是在你的EditText中。

为了更好地理解

<EditText
    android:id="@+id/edt_description"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textCapSentences"/>
    

在XML和JAVA文件中设置输入类型,

在XML中,

android:inputType=“textMultiLine|textCapSentences”

它也将允许多行和在JAVA文件,

edittext.setRawInputType(InputType.TYPE_CLASS_TEXT|InputType.TYPE_TEXT_FLAG_CAP_SENTENCES);

确保你键盘的自动大写设置是启用的。
