如何在android InputMethodService中添加自定义图像作为表情符号。 我尝试过使用
ImageGetter imageGetter = new ImageGetter() {
public Drawable getDrawable(String source) {
StringTokenizer st = new StringTokenizer(str, ".");
Drawable d = new BitmapDrawable(getResources(),emoticons[Integer.parseInt(st.nextToken()) - 1]);
d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
return d;
}
};
Spanned cs = Html.fromHtml("<img src ='"+ str +"'/>", imageGetter, null);
getCurrentInputConnection().commitText(cs,1);
但只获得 obj文本图片。 有没有办法在android
中添加自定义表情符号到消息(whatsapp / twitter)修改:
在我的应用程序中,如果我使用自定义键盘键入hello,我必须在编辑字段中为手机中安装的每个应用程序插入一个自定义的hello图片。
可以实现吗?

我已经使用convert mage检查了它到base64,但Tag
没有任何反应ImageGetter imageGetter = new ImageGetter() {
@Override
public Drawable getDrawable(String source) {
byte [] encodeByte=Base64.decode("iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==",Base64.DEFAULT);
Bitmap bitmap=BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
Drawable d = new BitmapDrawable(bitmap);
Log.e("Chk", "Height : "+d.getIntrinsicHeight());
Log.e("Chk", "Width : " + d.getIntrinsicWidth());
return d;
}
};
Spanned cs = Html.fromHtml("<img src='data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='/>", imageGetter,null);
Log.e("Chk", "12 : " + 12);
getCurrentInputConnection().setComposingText(cs,1);

您正在尝试将图片发送到twitter / whatsapp,而不是表情符号。它们是有区别的。
表情符号字面意思是“图片到字符”,并且取决于接收者正在使用的手机字符集。即使您更换了与您自己的手机表情符号相关联的图像,您发送表情符号的人也只能看到他们自己的表情符号键集。这不是你想要的。图像与手机密钥集无关,无论发送给哪些手机,图像都会大致相同。您需要将图像传递给与用户当前关注的应用程序关联的意图。
这是这里引用的应用程序:https://play.google.com/store/apps/details?id=com.plantpurple.emojidom最有可能做的事情。
