SeekBar小数增量

Question

我正在尝试创建一个搜索栏，用户可以在其中通知来自$0,000 to $10,000的价格。我已经尝试实现了这一行：float value = ((float)progress / 10.0);，但是android studio一直给我错误incompatible types Required: float Found: Double

代码如下：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        gas = (TextView) findViewById(R.id.gasTextView);
        SeekBar gasSeekBar = (SeekBar) findViewById(R.id.gasSeekBar);
        gasSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                float value = ((float)progress / 10.0);
                gas.setText("Gasolina: "+progress);
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }
        });

        etanol = (TextView) findViewById(R.id.etanolTextView);
        SeekBar etanolSeekBar = (SeekBar) findViewById(R.id.etanolSeekBar);
        etanolSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                etanol.setText("Etanol: "+progress);
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }
        });
    }

Answer 1

你可以使用下面的代码-(只需去掉小数)

    float value = ((float)progress / 10);

也不会有任何错误。

Answer 2

我觉得你的cast地址不正确...

怎么样

float value = (float)(progress / 10.0);
