长按复制TextView

public class MainActivity extends AppCompatActivity {    private TextView tv1;    private EditText ed2;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        tv1=(TextView)findViewById(R.id.tv1);        tv1.setOnLongClickListener(new View.OnLongClickListener() {            @Override            public boolean onLongClick(View v) {                ClipboardManager cmb = (ClipboardManager) getApplicationContext().getSystemService(Context.CLIPBOARD_SERVICE);                cmb.setText(tv1.getText().toString().trim()); //将内容放入粘贴管理器,在别的地方长按选择"粘贴"即可                Toast.makeText(getApplicationContext(),"已经复制",Toast.LENGTH_SHORT).show();                return false;            }        });    }}

这样就可以长按textView textView就在系统的粘贴板里边了
