有人能告诉我如何复制在一个特定的文本视图到剪贴板,当一个按钮被按下?

@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 :)
        }
    });
}

我想复制文本在TextView TextView到剪贴板时,按钮bCopy按下。


当前回答

您可以在onclick按钮事件时执行此复制到剪贴板功能。所以把这些代码行放在你的按钮onClickListerner

android.content.ClipboardManager clipboardManager = (android.content.ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clipData = android.content.ClipData.newPlainText("Text Label", ViewPass.getText().toString());
clipboardManager.setPrimaryClip(clipData);
Toast.makeText(getApplicationContext(),"Copied from Clipboard!",Toast.LENGTH_SHORT).show();

作为一个方便的kotlin扩展:

fun Context.copyToClipboard(text: CharSequence){
    val clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
    val clip = ClipData.newPlainText("label",text)
    clipboard.setPrimaryClip(clip)
}

更新:

如果你使用ContextCompat,你应该使用:

ContextCompat.getSystemService(this, ClipboardManager::class.java)

使用这段代码

   private ClipboardManager myClipboard;
   private ClipData myClip;
   TextView textView;
   Button copyText;

@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);
    myClipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);

    copyText.setOnClickListener(new View.OnClickListener() {


        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub


           String text = textView.getText().toString();
           myClip = ClipData.newPlainText("text", text);
           myClipboard.setPrimaryClip(myClip);
           Toast.makeText(getApplicationContext(), "Text Copied", 
           Toast.LENGTH_SHORT).show(); 
        }
    });
}

在Kotlin中,我有一个扩展

fun Context.copyToClipboard(text: String) {
  val clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
  val clip =
    ClipData.newPlainText(getString(R.string.copy_clipboard_label, getString(R.string.app_name)),text)
  clipboard.setPrimaryClip(clip)
}
    import android.content.ClipData
    import android.content.ClipboardManager
    import android.content.Context

    val clipboardManager = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
    clipboardManager.setPrimaryClip(ClipData.newPlainText("text","this is copied...paste it" ))

使用Jetpack Compose,这非常简单:

AmbientClipboardManager.current.setText(AnnotatedString("Copied Text"))
