1.在Application中获取ClipboardManager
public class MyApplication extends Application{ private static Application mApp; private static ClipboardManager mClipboardManager; @Override public void onCreate() { super.onCreate(); mApp = this; } public static ClipboardManager getClipboardManager(){ if (mClipboardManager == null) { mClipboardManager = (ClipboardManager) mApp.getSystemService(Context.CLIPBOARD_SERVICE); } return mClipboardManager; }}2.在工具类中添加弹出复制的Dialog
public class Utils { public static void showCopyDialog(Context context , final String content){ new AlertDialog.Builder(context) .setTitle("选项") .setItems(new String[]{"复制"}, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { MyApplication.getClipboardManager().setText(content); dialog.dismiss(); } }).show(); }}3.将TextView的内容复制到EditText中
public class MainActivity extends Activity implements OnClickListener{ private TextView mTextView; private EditText mEditText; private MyApplication mApp; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mApp = (MyApplication) getApplicationContext(); initViews(); registerListener(); } private void registerListener() { mTextView.setOnClickListener(this); } private void initViews() { mTextView = (TextView) findViewById(R.id.textView1); mEditText = (EditText) findViewById(R.id.editText1); } @Override public void onClick(View v) { mTextView.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Utils.showCopyDialog(MainActivity.this, mTextView.getText().toString()); } }); }}4.测试一下
