我在我的应用中使用Google的 Gboard ，当我从键盘应用输入 GIF 到我的EditText时，它会显示吐司< / p>
＆＃34;文本字段不支持从键盘插入GIF＆＃34;
我已经搜索过这一千次并且无法找到结果
任何帮助都将不胜感激。

Users often want to communicate with emojis, stickers, and other kinds of rich
content. In previous versions of Android, soft keyboards (also known as input
method editors or IMEs) could send only unicode emoji to apps. For rich
content, apps had to either build app-specific APIs that couldn't be used in
other apps or use workaround like sending images through Easy Share Action or the
clipboard.
键盘图像插入需要IME和 该应用程序。以下序列描述了图像中的每个步骤 插入过程：
当用户点击EditText时，编辑器会发送MIME列表 它在EditorInfo.contentMimeTypes中接受的内容类型。
IME读取支持的类型列表并显示内容 编辑器可以接受的软键盘。
当用户选择图像时，IME调用commitContent（）和 将InputContentInfo发送给编辑器。 commitContent（）调用是 类似于commitText（）调用，但是对于丰富的内容。 InputContentInfo包含一个标识a中内容的URI 内容提供商。然后，您的应用可以请求权限并阅读 来自URI的内容。
To accept rich content from IMEs, apps must tell IMEs what content types it
accepts and specify a callbackup method that is executed when content is
received. The following example demonstrates how to create an EditText that
accept PNG images:
EditText editText = new EditText(this) {
@Override
public InputConnection onCreateInputConnection(EditorInfo editorInfo) {
final InputConnection ic = super.onCreateInputConnection(editorInfo);
EditorInfoCompat.setContentMimeTypes(editorInfo,
new String [] {"image/png"});
final InputConnectionCompat.OnCommitContentListener callback =
new InputConnectionCompat.OnCommitContentListener() {
@Override
public boolean onCommitContent(InputContentInfoCompat inputContentInfo,
int flags, Bundle opts) {
// read and display inputContentInfo asynchronously
if (BuildCompat.isAtLeastNMR1() && (flags &
InputConnectionCompat.INPUT_CONTENT_GRANT_READ_URI_PERMISSION) != 0) {
try {
inputContentInfo.requestPermission();
}
catch (Exception e) {
return false; // return false if failed
}
}
// read and display inputContentInfo asynchronously.
// call inputContentInfo.releasePermission() as needed.
return true; // return true if succeeded
}
};
return InputConnectionCompat.createWrapper(ic, editorInfo, callback);
}
};
以下是完整文档参考
https://developer.android.com/guide/topics/text/image-keyboard.html#how_it_works
想要向应用程序发送丰富内容的IME必须实现 提交内容API，如下所示：
覆盖
onStartInput()或onStartInputView()并阅读列表 目标编辑器支持的内容类型。以下代码 代码段显示了如何检查目标编辑器是否接受GIF 图像。的
@Override
public void onStartInputView(EditorInfo info, boolean restarting) {
String[] mimeTypes = EditorInfoCompat.getContentMimeTypes(editorInfo);
boolean gifSupported = false;
for (String mimeType : mimeTypes) {
if (ClipDescription.compareMimeTypes(mimeType, "image/gif")) {
gifSupported = true;
}
}
if (gifSupported) {
// the target editor supports GIFs. enable corresponding content
} else {
// the target editor does not support GIFs. disable corresponding content
}
}
用户选择图片时向应用提交内容。避免 在有任何撰写文本时调用
commitContent()因为它 可能会导致编辑失去焦点。以下代码段显示 如何提交GIF图像。
/**
* Commits a GIF image
*
* @param contentUri Content URI of the GIF image to be sent
* @param imageDescription Description of the GIF image to be sent
*/
public static void commitGifImage(Uri contentUri, String imageDescription) {
InputContentInfoCompat inputContentInfo = new InputContentInfoCompat(
contentUri,
new ClipDescription(imageDescription, new String[]{"image/gif"}));
InputConnection inputConnection = getCurrentInputConnection();
EditorInfo editorInfo = getCurrentInputEditorInfo();
Int flags = 0;
if (android.os.Build.VERSION.SDK_INT >= 25) {
flags |= InputConnectionCompat.INPUT_CONTENT_GRANT_READ_URI_PERMISSION;
}
InputConnectionCompat.commitContent(
inputConnection, editorInfo, inputContentInfo, flags, opts);
}

我从某个地方找到了解决方案。希望它能帮助每个人。
exports.register = functions.https.onRequest((request, response) => {
const db = admin.firestore();
const user: string = request.body['username'];
const phone: number = request.body['phone'];
const password: string = request.body['password'];
return db.collection('rejectedContacts').where('contact', '==', phone).get()
.then(rejectedContactsSnapShot => {
if (rejectedContactsSnapShot.size > 0) {
return response.json(
{
status: 0,
message: `Contact, ${phone} is blocked, please try again with another number`,
result: null
}
);
}
}).then(notRejected=>{
return db.collection('users').where('contacts.phone', '==', phone).get()
.then(contactsSnapShot => {
if (contactsSnapShot.size > 0) {
return response.json(
{
status: 0,
message: `Contact, ${phone} is already assigned with an account. Did you forgot your pasword?`,
result: null
}
);
}
});
}).then(numberDoesNotExists=>{
return db.collection('users').add(
{
user: user,
password: password,
isBlocked: false,
joiningDate: Date.now(),
phoneVerified: false,
deleted: false,
contacts:

}
}
);
}).then((writeResult) => {
return response.json(
{
result: `User with ID: ${writeResult.id} added.`
}
);
});
});

如果您想要内置具有此功能的EditText，请签出我的库RichContentEditText：https://github.com/GregoryConrad/RichContentEditText
它毫不费力地允许将丰富的内容（图像和其他文件）从IME传输到应用程序。这是一些示例代码：
ffmpeg -i 1_a.opus -i 2_a.opus -i 1_v.mp4 -i 2_v_bars.mp4 -filter_complex "[1:a]adelay=15720|15720[a1]; [0:a][a1]amix; [3:v]trim=0:15.81,geq=0:128:128,fifo [silence]; [silence][3:v]concat,fifo [3_v_silence]; [3_v_silence][2:v]hstack,fifo" -vcodec libx264 -strict experimental -y out_fifo_h264_2.mp4
