setOnLongClickListener 返回值的作用

直接说结果：返回值是false（默认）则长按时执行完长按监听之后会走点击的监听

返回值是true 则长按时只会执行setOnLongClickListener

下面是验证，可以不看- -。

MainActivity

public class MainActivity extends AppCompatActivity implements View.OnClickListener, View.OnLongClickListener {    private Button btn1, btn2;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        btn1 = (Button) findViewById(R.id.btn1);        btn2 = (Button) findViewById(R.id.btn2);        btn1.setOnClickListener(this);        btn2.setOnClickListener(this);        btn1.setOnLongClickListener(this);        btn2.setOnLongClickListener(this);    }    @Override    public void onClick(View view) {        Toast.makeText(this, "短按", Toast.LENGTH_SHORT).show();    }    @Override    public boolean onLongClick(View view) {        switch (view.getId()) {            case R.id.btn1:                Toast.makeText(this, "长按", Toast.LENGTH_SHORT).show();                return false;            case R.id.btn2:                Toast.makeText(this, "长按", Toast.LENGTH_SHORT).show();                return true;        }        return true;    }}
