Java：类型转换问题

Question

Is there any way to do this in a single line:

    TextView tv = (TextView) findViewById(R.id.lbSightName);
    tv.setText("Some Text");

I would like to do away declaring the intermediary tv, like so:

(TextView) findViewById(R.id.lbSightName).setText("Some Text");

Not possible?

Answer 1

You can, but it isn't best practice

((TextView) findViewById(R.id.lbSightName)).setText("Some Text");
TextView.class.cast(findViewById(R.id.lbSightName).setText("Some Text");

Answer 2

((TextView) findViewById(R.id.lbSightName)).setText("Some Text");

Answer 3

再加上一组括号，应该可以：

((TextView)findViewById(R.id.lbSightName)).setText("Some Text");

Answer 4

((TextView) findViewById(R.id.lbSightName)).setText("Some Text");

只需添加括号。

Answer 5

当然

((TextView) findViewById(R.id.lbSightName)).setText("Some Text");

Answer 6

((TextView)findViewById(R.id.lbSightName)).setText("Some thingy");

再加上一组括号就可以了
