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.

testEditText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_CAP_WORDS);   

或者android:inputType=" textcapsentence "将只工作,如果你的设备键盘自动大写设置启用。

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);
        }
    }
};

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…

要大写,您可以对编辑文本执行以下操作:

大写:使每个单词的第一个字母大写:

android:inputType="textCapWords"

使每个句子的第一个字母大写:

android:inputType="textCapSentences"

使每个字母大写:

android:inputType="textCapCharacters"

但这只会改变键盘和用户可以改变模式写小写字母。

因此,如果你真的想要大写格式的数据,这种方法不太受欢迎,首先添加以下类:

public class CapitalizeFirstLetter {
    public static String capitaliseName(String name) {
        String collect[] = name.split(" ");
        String returnName = "";
        for (int i = 0; i < collect.length; i++) {
            collect[i] = collect[i].trim().toLowerCase();
            if (collect[i].isEmpty() == false) {
                returnName = returnName + collect[i].substring(0, 1).toUpperCase() + collect[i].substring(1) + " ";
            }
        }
        return returnName.trim();
    }
    public static String capitaliseOnlyFirstLetter(String data)
    {
        return data.substring(0,1).toUpperCase()+data.substring(1);
    }
}

然后,

现在把每个单词都大写:

CapitalizeFirstLetter.capitaliseName(name);

只大写第一个词:

CapitalizeFirstLetter.capitaliseOnlyFirstLetter(data);

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。
