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。

如果你想从edittext中复制文本,那么首先创建edittext

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

然后创建一个按钮,点击后,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

Java

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()

        }

确保导入这个

import android.content.ClipboardManager;

不要导入这个

android.text.ClipboardManager

使用此函数复制到剪贴板

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");
}

对于Jetpack编写

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

这可以在Kotlin中像这样完成:

var clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
var clip = ClipData.newPlainText("label", file.readText())
clipboard.setPrimaryClip = clip

file.readText()是你的输入字符串。

只需编写以下代码:

clipboard.setText(getstring);

使用Jetpack Compose,这非常简单:

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