EditText的首字母大写

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.

对于EditText中的资本化，您可以选择以下两种输入类型:

android：inputType=“textCapSentences” android：inputType=“textCapWords”

textCapSentences 这将使每个句子中第一个单词的第一个字母成为大写字母。

textCapWords 这将使每个单词的第一个字母作为大写字母。

如果你想要两个属性都使用|符号

android:inputType="textCapSentences|textCapWords"

使用此代码仅第一个字母大写的EditText

MainActivity.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <EditText
        android:id="@+id/et"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:tag="true">
    </EditText>

</RelativeLayout>

MainActivity.java

EditText et = findViewById(R.id.et);
        et.addTextChangedListener(new TextWatcher() {
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            }

            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2)
            {
                if (et.getText().toString().length() == 1 && et.getTag().toString().equals("true"))
                {
                    et.setTag("false");
                    et.setText(et.getText().toString().toUpperCase());
                    et.setSelection(et.getText().toString().length());
                }
                if(et.getText().toString().length() == 0)
                {
                    et.setTag("true");
                }
            }

            public void afterTextChanged(Editable editable) {

            }
        });

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。

以前它是android:capitalize="words"，现在已弃用。建议使用android:inputType="textCapWords"

请注意，这将只在您的设备键盘自动大写设置启用。

要通过编程实现，请使用以下方法:

setInputType (InputType。TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_CAP_WORDS);

在XML编辑文本中应用以下行。

android:inputType="textCapSentences|textMultiLine"

它还允许多线支持。
