Android自定义键盘布局在侧面留下白色边缘
use*_*043 11 xml keyboard android ime
我正在研究Android的自定义键盘,我遇到了一个问题,键盘似乎在右边留下一个白线/空格,而不是填充父视图...(不要介意图标,它现在只是占位符图形)
下面你可以看到我的布局......
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
android:keyWidth="14%p"
android:horizontalGap="0px"
android:verticalGap="0px"
android:keyHeight="60dp"
>
<Row>
<Key android:codes="49" android:keyIcon="@drawable/rsz_emoji" android:horizontalGap="1%p" android:keyEdgeFlags="left"/>
<Key android:codes="50" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="51" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="52" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="53" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="54" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="48" android:keyIcon="@drawable/rsz_emoji" android:keyEdgeFlags="right"/>
</Row>
<Row>
<Key android:codes="113" android:keyIcon="@drawable/rsz_emoji" android:horizontalGap="8%p" android:keyEdgeFlags="left"/>
<Key android:codes="114" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="116" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="121" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="111" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="112" android:keyIcon="@drawable/rsz_emoji" android:keyEdgeFlags="right"/>
</Row>
<Row>
<Key android:codes="1" android:keyIcon="@drawable/rsz_emoji" android:keyWidth="28%p" android:horizontalGap="8%p" android:keyEdgeFlags="left"/>
<Key android:codes="46" android:keyIcon="@drawable/rsz_emoji" android:keyWidth="28%p"/>
<Key android:codes="58" android:keyIcon="@drawable/rsz_emoji" android:keyWidth="28%p" android:keyEdgeFlags="right"/>
</Row>
<Row android:rowEdgeFlags="bottom">
<Key android:codes="44" android:keyIcon="@drawable/globe" android:horizontalGap="8%p" android:keyEdgeFlags="left"/>
<Key android:codes="47" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="32" android:keyIcon="@drawable/rsz_emoji" android:keyWidth="28%p"/>
<Key android:codes="1" android:keyIcon="@drawable/rsz_emoji"/>
<Key android:codes="-5" android:keyIcon="@drawable/backspace" android:keyEdgeFlags="right"/>
</Row>
</Keyboard>
据我所知,这是一个问题1%p...但我有点不确定如何填补它而不会弄乱我的路线......例如将第一行的间隙改为2会修复它,但是搞砸了对齐.
根据要求为您添加了额外的代码......
我的班级延伸InputMethodService:
private KeyboardView kv;

@Override
public View onCreateInputView() {
kv = (KeyboardView)getLayoutInflater().inflate(R.layout.keyboard, null);
keyboard = new Keyboard(this, R.xml.custom_keyboard);
kv.setPreviewEnabled(false);
kv.setKeyboard(keyboard);
kv.setOnKeyboardActionListener(this);
return kv;
}
@Override
public void onPress(int primaryCode) {
}
@Override

}
@Override

InputConnection ic = getCurrentInputConnection();
if (primaryCode == Keyboard.KEYCODE_DELETE) {
ic.deleteSurroundingText(1, 0);
} else {

Bitmap mBitmap = ((BitmapDrawable)mDrawable).getBitmap();
String path = MediaStore.Images.Media.insertImage(getContentResolver(), mBitmap, "Emoticon", null);
Uri fileUri = Uri.parse(path);
Intent picMessageIntent = new Intent(Intent.ACTION_SEND);
picMessageIntent.setPackage("com.android.mms");
picMessageIntent.putExtra(Intent.EXTRA_STREAM, fileUri);
picMessageIntent.setType("image/png");
picMessageIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

我无法重现错误,我提供了截图,带有浅色背景应用程序和所有相关代码.如果没有看到整个项目和目录,我不确定你到底出了什么问题,所以我发布了相关的xml.还有一个服务类,我没有包括(因为你显然有它工作).
该<Keyboard>代码是在一个名为qwerty.xml在资源/ XML文件夹与文件名为method.xml:
我在qwerty.xml中使用了所有键盘尺寸,除了我替换了图像.
method.xml
<?xml version="1.0" encoding="utf-8"?>
<input-method xmlns:android="http://schemas.android.com/apk/res/android">
<subtype
android:label="@string/subtype_en_US"
android:imeSubtypeLocale="en_US"
android:imeSubtypeMode="keyboard" />
</input-method>
两个布局文件:
keyboard.xml
<?xml version="1.0" encoding="UTF-8"?>
<android.inputmethodservice.KeyboardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/keyboard"
android:layout_width="match_parent"

android:layout_alignParentBottom="true"
android:keyPreviewLayout ="@layout/preview"
/>
preview.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:gravity="center"
android:textSize="30sp
android:textStyle="bold">

样式:
<resources>

<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>

</resources>
在清单中,在应用程序中:
<service
android:name=".SimpleIME"
android:label="@string/simple_ime"
android:permission="android.permission.BIND_INPUT_METHOD"
>
<meta-data
android:name="android.view.im"
android:resource="@xml/method"/>
<intent-filter>
<action android:name="android.view.InputMethod"/>
</intent-filter>
</service>
我把图像留得太大,所以你可以清楚地看到没有间隙.

在评论中讨论后,我建议检查您的背景样式,因为键盘窗口可能会显示默认背景颜色的问题/更改.本回答/sf/answers/2313685391/中详细讨论了这个问题.我不会重申细节,因为这个链接不太可能腐烂,是一个受欢迎的SO帖子.

确定在输入法服务中添加差异:
@Override
public void onKey(int primaryCode, int[] keyCodes) {
InputConnection ic = getCurrentInputConnection();
switch(primaryCode){
case Keyboard.KEYCODE_DELETE :
ic.deleteSurroundingText(1, 0);
break;
case Keyboard.KEYCODE_SHIFT:
caps = !caps;
keyboard.setShifted(caps);
kv.invalidateAllKeys();
break;
case Keyboard.KEYCODE_DONE:
ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));
break;
default:
char code = (char)primaryCode;
if(Character.isLetter(code) && caps){
code = Character.toUpperCase(code);
}
ic.commitText(String.valueOf(code),1);
}
}

创建一个空白项目,没有键盘活动,测试并将其作为单独的应用程序运行.您正在使用android:theme="@style/AppTheme.NoActionBar"在启动器活动中,可能存在背景不透明度和窗口/视图的问题.
在您的情况下：7（键）x 14% = 98% + 1% 间隙 (firstkey\xc5\x9b horizontalGap) = 99%。
将“%1”放入horizontalGap最后一个键中，就像在第一个键中所做的那样。
