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.

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。

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) {

            }
        });

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

如果您在styles.xml中编写样式,那么

删除android:inputType属性并添加以下行

<item name="android:capitalize">words</item>
