android - Android 从剪贴板管理器复制/粘贴

Question

是否可以发送过去的命令，以便将文本粘贴到当前聚焦的编辑文本中。设想：

后台服务监听通知（完成）
收到通知时需要将文本复制到剪贴板（完成）
将文本粘贴到任何当前聚焦的字段，如果不可能，只需丢弃粘贴命令。

我知道如何用复制文本ClipboardManager，但我不知道如何粘贴它。

您可以使用以下代码复制和粘贴文本：

复制：

ClipboardManager clipboard = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText("your_text_to_be_copied");
clipboard.setPrimaryClip(clip);

并粘贴它：

ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
String pasteData = "";

 // If it does contain data, decide if you can handle the data.
if (!(clipboard.hasPrimaryClip())) {

} else if (!(clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_PLAIN))) {

    // since the clipboard has data but it is not plain text

} else {

    //since the clipboard contains plain text.
    ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);

    // Gets the clipboard as text.
    pasteData = item.getText().toString(); 
}

如果您只想将一些代码“复制并粘贴”到您的应用程序中，您可以使用以下内容。

＃复制

String textToCopy = etCodeWindow.getText().toString();

ClipboardManager clipboard = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText(null, textToCopy);
if (clipboard == null) return;
clipboard.setPrimaryClip(clip);

＃粘贴

获取要粘贴的文本

ClipboardManager clipboard = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
if (clipboard == null) return;
ClipData clip = clipboard.getPrimaryClip();
if (clip == null) return;
ClipData.Item item = clip.getItemAt(0);
if (item == null) return;
CharSequence textToPaste = item.getText();
if (textToPaste == null) return;

或者

ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
try {
    CharSequence textToPaste = clipboard.getPrimaryClip().getItemAt(0).getText();
} catch (Exception e) {
    return;
}

或在Kotlin中相同：

val clipboard = (getSystemService(Context.CLIPBOARD_SERVICE)) as? ClipboardManager
val textToPaste = clipboard?.primaryClip?.getItemAt(0)?.text ?: return false

在光标位置插入

如果有选择，则选择将替换为粘贴文本。

int start = Math.max(myEditText.getSelectionStart(), 0);
int end = Math.max(myEditText.getSelectionEnd(), 0);
myEditText.getText().replace(Math.min(start, end), Math.max(start, end),
            textToPaste, 0, textToPaste.length());

＃笔记

此答案假定您不再支持 API 11 之前的版本。如果您支持，请查看编辑历史记录。
导入android.content.ClipboardManager和android.content.ClipData.
我以前只是将粘贴文本放在一个衬里，直到我发现 ClipData 有时会导致 NPE 崩溃。现在我要么使用 try/catch 块，要么更仔细地检查空值。

在蜂窝 >= API 13 之后对上述内容的简短总结：

public String readFromClipboard() {
    ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
    if (clipboard.hasPrimaryClip()) {
        android.content.ClipDescription description = clipboard.getPrimaryClipDescription();
        android.content.ClipData data = clipboard.getPrimaryClip();
        if (data != null && description != null && description.hasMimeType(ClipDescription.MIMETYPE_TEXT_PLAIN)) 
            return String.valueOf(data.getItemAt(0).getText());
    }
    return null;
}

为了以编程方式复制粘贴的最佳和简单的方法是......

创建一个 Button 并将此代码复制到 onclicklistener 中。

ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);

复印

clipboard.setText("which you want to copy");

用于粘贴

textview1.setText(clipboard.getText().toString());

这是@Suragch 答案的附录。

在科特林：

        val clipboard = (getSystemService(Context.CLIPBOARD_SERVICE)) as? ClipboardManager
        val textToPaste = clipboard?.primaryClip?.getItemAt(0)?.text ?: return

        binding.<your paste button camelCase id>.setOnClickListener {
            if (clipboard.hasPrimaryClip()) {
                binding.<your EditText camelCase id>.setText(textToPaste)
            }
        }

Fragment 内部：getSystemService() 是 Context 类的方法，需要先调用 Context。可以使用 getContext() 或 getActivity() - Activity 也是一个上下文。

this.activity.getSystemService(...)
this.context.getSystemService(...)

或者：

activity.getSystemService(...)
context.getSystemService(...)

另外请记住只有安全 (?.) 或非空断言 (!!.) 调用。如果你不想让用户禁食你可以指定的任何数据，fe：

if (clipboard.hasPrimaryClip() && textToPaste.isDigitsOnly())

对于大多数 Android 设备，在 Honeycomb Android 3.0 以上版本以下代码将起作用

用于将文本复制到剪贴板

ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); 
        ClipData clip = android.content.ClipData
                    .newPlainText("copyingToClipboard", "your text here to be copied to clipboard");
    clipboard.setPrimaryClip(clip);

从剪贴板复制

ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
        if (clipboard.hasPrimaryClip() && (clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_PLAIN) || clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_HTML))) {
            ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);
            String clipboardtext = item.getText().toString();
            Toast.makeText(Context,clipboardtext,Toast.LENGTH_LONG).show();
        }

如果剪贴板不包含任何数据，代码将避免空值异常。
