Android keyboard - start lowercase

问题:

Is it possible to start android keyboard with lowercase when I click on EditText? Basically, what I want is to lowercase the first letter in EditText, but also to give user an possibility to make it uppercase if he want...

(EditText input is and must be multiline text)

EDIT:

            <EditText
                android:id="@+id/txt_str"
                android:inputType="text|textMultiLine"
                android:maxLines="1"
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="match_parent"
                android:hint="@string/enter_txt_here"
                android:textIsSelectable="true"
                android:layout_marginRight="6dp"
                android:paddingLeft="6dp"
                android:paddingRight="6dp"
                android:textSize="17sp"
                android:textColor="#FFFFFF"
                android:textColorHint="#FFFFFF"
                android:gravity="center_vertical"
                android:background="@drawable/txt_card_selector"
                android:ellipsize="start" />

EDIT2
I think this is not possible when text must be multiline...

回答1:

Yes that is possible. Try researching the EditText Input Types.

For example you force the keyboard default state as lower case by simply:

EditText text = new EditText(context);
text.setInputType(android.text.InputType.TYPE_CLASS_TEXT | android.text.InputType.TYPE_TEXT_FLAG_MULTI_LINE);

Or if you want to force capitalization for every sentense:

EditText text = new EditText(context);
text.setInputType(android.text.InputType.TYPE_CLASS_TEXT | android.text.InputType.TYPE_TEXT_FLAG_CAP_SENTENCES);

You can find a whole list types here.

Using xml you can force keyboard to make lowercase

android:inputType="text|textEmailAddress"

回答3:

As this page says: Initial keyboard on lowercase

Set input type to email addres:

Text.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS);

回答4:

Using

text.setInputType(text.InputType.TYPE_CLASS_TEXT | text.InputType.TYPE_TEXT_FLAG_MULTI_LINE);

or

text.setInputType(text.InputType.TYPE_CLASS_TEXT | text.InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS);

Did not work for me. What actually did it was this:

text.setInputType(inputEditText.getInputType() | InputType.TYPE_TEXT_FLAG_CAP_CHARACTERS); // forced capitalization
text.setInputType(inputEditText.getInputType() & ~ InputType.TYPE_TEXT_FLAG_CAP_CHARACTERS); // negate the flag
