有人可以告诉我如何在按下按钮时将特定文本视图中的文本复制到剪贴板吗? Thanx:)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainpage);
textView = (TextView) findViewById(R.id.textview);
copyText = (Button) findViewById(R.id.bCopy);
copyText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
String getstring = textView.getText().toString();
//Help to continue :)
}
});
}
}
我想在按下按钮bCopy时将TextView textView中的Text复制到剪贴板!请帮忙......

ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText(label, text);
clipboard.setPrimaryClip(clip);
确保您已导入android.content.ClipboardManager
而非android.text.ClipboardManager
。后者已被弃用。
请查看此link以获取更多信息。

这里是将文本复制到剪贴板的方法:
private void setClipboard(Context context, String text) {
if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB) {
android.text.ClipboardManager clipboard = (android.text.ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
clipboard.setText(text);
} else {
android.content.ClipboardManager clipboard = (android.content.ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData.newPlainText("Copied Text", text);
clipboard.setPrimaryClip(clip);
}
}
此方法适用于所有Android设备。

请使用此功能。它只适用于android api&gt; = 11之前你必须使用ClipData。
ClipboardManager _clipboard = (ClipboardManager) _activity.getSystemService(Context.CLIPBOARD_SERVICE);
_clipboard.setText(YOUR TEXT);
希望它能帮到你:)。

就像Ujjwal Singh所说的方法setText
现在已被弃用,您应该使用,就像文档推荐的那样,setPrimaryClip(clipData)

作为方便的Kotlin扩展名:

这可以在Kotlin中完成,如下所示:
var clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
var clip = ClipData.newPlainText("label", file.readText())
clipboard.primaryClip = clip
file.readText()
是您的输入字符串。

答案 11 :(得分:1)
使用此方法:
ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText(label, text);
clipboard.setPrimaryClip(clip);
在setPrimaryClip处,我们还可以使用以下方法:
void clearPrimaryClip()
清除剪贴板上当前的所有主剪辑。
ClipData getPrimaryClip()
返回剪贴板上的当前主剪辑。
ClipDescription getPrimaryClipDescription()
返回剪贴板上当前主剪辑的描述,而不是其数据的副本。
CharSequence getText()
不推荐使用此方法。使用getPrimaryClip()代替。这将检索主剪辑,并尝试将其强制为字符串。
boolean hasPrimaryClip()
如果剪贴板上当前有一个主剪辑,则返回true。

如果你想让它更短,请使用:
ClipData clip = ClipData.newPlainText(label, text);

要搜索剪贴板列表,首先像这样获取剪贴板对象:
private val clipboard = context.getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
然后通过这个函数检查剪贴板中是否有任何数据:
fun isClipboardContainsData() : Boolean{
return when{
!clipboard.hasPrimaryClip() -> false
else -> true
}
}
然后使用此函数遍历剪贴板对象,如下所示:
fun searchClipboard() : ClipData.Item? {
return if (isClipboardContainsData()){
val items = clipboard.primaryClip
val clipboardSize = items?.itemCount ?: 0
for (i in 0..clipboardSize) {
val item = items?.getItemAt(i)
return if (item != null){
return item
}else
null
}
return null
}else
null
}
在这里你可以看到 searchClipboard Item 将返回一个 ClipData.Item 类型的项目,剪贴板包含一个 ClipData.Item 的列表,如果你完成了剪贴板的实现,你会发现关于 ClipData.Item 的内容:< /p>
public static class Item {
final CharSequence mText;
final String mHtmlText;
final Intent mIntent;
@UnsupportedAppUsage(maxTargetSdk = Build.VERSION_CODES.P, trackingBug = 115609023)
Uri mUri;
}
因此您可以在剪贴板项目中保存的内容可能是以下类型:

android.content.ClipData data = clipboard.getPrimaryClip();
if (data != null && description != null && description.hasMimeType(ClipDescription.MIMETYPE_TEXT_PLAIN))
