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。

Kotlin助手方法附加单击复制TextView上的文本

把这个方法放在Util类中的某个地方。这个方法附加点击监听器的textview复制内容的textview到一个clipText点击该textview

/**
 * Param:  cliplabel, textview, context
 */
fun attachClickToCopyText(textView: TextView?, clipLabel: String, context: Context?) {
    if (textView != null && null != context) {
        textView.setOnClickListener {
            val clipboard = context.getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
            val clip = ClipData.newPlainText(clipLabel, textView!!.text)
            clipboard.primaryClip = clip
            Snackbar.make(textView,
                    "Copied $clipLabel", Snackbar.LENGTH_LONG).show()
        }
    }

}

如果你想让它更短,使用:

ClipData clip = ClipData.newPlainText(label, text);
((ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE)).setPrimaryClip(clip);

int sdk = android.os.Build.VERSION.SDK_INT;

    if (sdk < android.os.Build.VERSION_CODES.HONEYCOMB) {
        android.text.ClipboardManager clipboard = (android.text.ClipboardManager) DetailView.this
                .getSystemService(Context.CLIPBOARD_SERVICE);
        clipboard.setText("" + yourMessage.toString());
        Toast.makeText(AppCstVar.getAppContext(),
                "" + getResources().getString(R.string.txt_copiedtoclipboard),
                Toast.LENGTH_SHORT).show();
    } else {
        android.content.ClipboardManager clipboard = (android.content.ClipboardManager) DetailView.this
                .getSystemService(Context.CLIPBOARD_SERVICE);
        android.content.ClipData clip = android.content.ClipData
                .newPlainText("message", "" + yourMessage.toString());
        clipboard.setPrimaryClip(clip);
        Toast.makeText(AppCstVar.getAppContext(),
                "" + getResources().getString(R.string.txt_copiedtoclipboard),
                Toast.LENGTH_SHORT).show();
    }

Kotlin扩展函数2021:

fun Context.copyToClipboard(text: CharSequence){
    val clipboard = ContextCompat.getSystemService(this,ClipboardManager::class.java)
    clipboard?.setPrimaryClip(ClipData.newPlainText("",text))
}
