复制

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。情形：

后台服务侦听通知（已完成）
收到通知时，需要将文本复制到剪贴板（已完成）
将文本粘贴到任何当前关注的字段，如果不可能，只需放弃粘贴命令。

我知道如何使用ClipboardManager复制文字，但我不知道如何粘贴它。

Answer 1

您可以使用以下代码复制和粘贴文字：

复制：

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

并粘贴：

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(); 
}

蜂窝后的上述简短概述＆gt; = API 13：

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;
}

Answer 3

如果您只想复制并粘贴＆＃34;一些代码进入您的应用程序，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

获取要粘贴的文字

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

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

将其插入光标位置

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());

注释

此答案假定您不再支持pre-API 11.如果您再查看编辑历史记录。
导入android.content.ClipboardManager和android.content.ClipData。
我曾经只是在一个衬里中获取粘贴文本，直到我发现ClipData有时会发生NPE崩溃。现在我要么使用try / catch块，要么更仔细地检查空值。

Answer 5

ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); 
String copyedText = clipboard.getText();

Answer 6

对于以编程方式复制粘贴的最佳简便方法是...

创建一个按钮，并将此代码复制到onclicklistener中。

ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);

用于复制

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

用于粘贴

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

Answer 7

对于大多数Android设备（高于Honeycomb Android 3.0版），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);

用于从剪贴板复制

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，该代码将避免空值异常。

Answer 8

这是@Suragch 答案的附录。

在 Kotlin 中：

        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 类上的一个方法，需要先调用 Context。可以通过使用 getContext() 或 getActivity() - Activity 也是一个上下文。

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

或者：

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

另外请记住仅安全 (?.) 或非空断言 (!!.) 调用。如果您不想让用户存储任何数据，您可以指定它，例如：

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

从剪贴板管理器复制/粘贴Android
