如何在Android中将文本复制到剪贴板？

Question

任何人都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？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......

Answer 1

使用ClipboardManager

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

确保你已导入android.content.ClipboardManager而不是android.text.ClipboardManager.后者已被弃用.请查看此链接以获取更多信息.

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.

        // Finally, if all we have is an Intent, then we can just turn that

Answer 4

对于 Jetpack Compose

val localClipboardManager = LocalClipboardManager.current
localClipboardManager.setText(AnnotatedString("Your text here"))

Answer 5

作为方便的Kotlin扩展：

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

更新：

如果使用ContextCompat，则应使用：

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

Answer 6

只需使用它.它只适用于android api> = 11之前你必须使用ClipData.

ClipboardManager _clipboard = (ClipboardManager) _activity.getSystemService(Context.CLIPBOARD_SERVICE);
_clipboard.setText(YOUR TEXT);

希望它能帮助你:)

[更新2015年3月19日]就像Ujjwal Singh说的那样,这个方法setText现在已经弃用了,你应该使用,正如文档推荐的那样,setPrimaryClip(clipData)

Answer 7

Kotlin 扩展函数 2021：

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

Answer 8

使用此代码

   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(); 
        }
    });
}

Answer 9

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()你的输入字符串在哪里.

Answer 10

@SuppressLint({ "NewApi", "NewApi", "NewApi", "NewApi" })
@SuppressWarnings("deprecation")
@TargetApi(11)
public void onClickCopy(View v) {   // User-defined onClick Listener
    int sdk_Version = android.os.Build.VERSION.SDK_INT;
    if(sdk_Version < android.os.Build.VERSION_CODES.HONEYCOMB) {
        android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
        clipboard.setText(textView.getText().toString());   // Assuming that you are copying the text from a TextView
        Toast.makeText(getApplicationContext(), "Copied to Clipboard!", Toast.LENGTH_SHORT).show();
    }
    else { 
        android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); 
        android.content.ClipData clip = android.content.ClipData.newPlainText("Text Label", textView.getText().toString());
        clipboard.setPrimaryClip(clip);
        Toast.makeText(getApplicationContext(), "Copied to Clipboard!", Toast.LENGTH_SHORT).show();
    }   
}

Answer 11

使用此功能复制到剪贴板

public void copyToClipboard(String copyText) {
    int sdk = android.os.Build.VERSION.SDK_INT;
    if (sdk < android.os.Build.VERSION_CODES.HONEYCOMB) {
        android.text.ClipboardManager clipboard = (android.text.ClipboardManager)
                getSystemService(Context.CLIPBOARD_SERVICE);
        clipboard.setText(copyText);
    } else {
        android.content.ClipboardManager clipboard = (android.content.ClipboardManager)
                getSystemService(Context.CLIPBOARD_SERVICE);
        android.content.ClipData clip = android.content.ClipData
                .newPlainText("Your OTP", copyText);
        clipboard.setPrimaryClip(clip);
    }
    Toast toast = Toast.makeText(getApplicationContext(),
            "Your OTP is copied", Toast.LENGTH_SHORT);
    toast.setGravity(Gravity.BOTTOM | Gravity.RIGHT, 50, 50);
    toast.show();
    //displayAlert("Your OTP is copied");
}

Answer 12

如果你想从 edittext 复制文本，那么首先创建 Edittext

    EditText mResultEt = findViewById(R.id.resultEt);

然后创建一个按钮，单击后我们可以复制这些文本

    ImageButton copyClipBoard = findViewById(R.id.btn_copy);

然后使用按钮的监听器

爪哇

copyClipBoard.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                ClipboardManager clipboardManager = (ClipboardManager)
                        getSystemService(Context.CLIPBOARD_SERVICE);
                ClipData clipData = ClipData.newPlainText("nonsense_data",
                        mResultEt.getText().toString());
                clipboardManager.setPrimaryClip(clipData);
                Toast.makeText(MainActivity.this, R.string.copied_to_clipboard, Toast.LENGTH_SHORT).show();
            }
        });

科特林

btn1.setOnClickListener{
            val clipboardManager = getSystemService(CLIPBOARD_SERVICE) as ClipboardManager
            val clipData = ClipData.newPlainText(
                "nonsense_data",
                content_et.getText().toString()
            )
            clipboardManager.setPrimaryClip(clipData)
            Toast.makeText(this@MainActivity, R.string.copied_to_clipboard, Toast.LENGTH_SHORT).show()

        }

并确保导入这个

import android.content.ClipboardManager;

不要导入这个

android.text.ClipboardManager
