android studio利用ProgressBar、SeekBar、RatingBar控件设计一个有关进度、滑动、星形等级评价功能界面，添加一个ImageView控件，通过拖拉滑动条对Imageview显示的图片的透明度进行设置，利用RatingBar实现一个等级评价功能，给出详细代码

好的，我知道了。下面是您所需要的代码：

XML文件：

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <ImageView
            android:id="@+id/imageView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/ic_launcher_background" />

        <SeekBar
            android:id="@+id/seekBar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:max="255"
            android:layout_alignParentBottom="true"/>

    </RelativeLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center">

        <ProgressBar
            android:id="@+id/progressBar"
            style="?android:attr/progressBarStyleHorizontal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="50dp"
            android:layout_marginRight="50dp"
            android:layout_weight="1"
            android:max="100"
            android:progress="0" />

        <RatingBar
            android:id="@+id/ratingBar"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:numStars="5"
            android:stepSize="1.0" />

    </LinearLayout>

</LinearLayout>

Java文件：

public class MainActivity extends AppCompatActivity {

    private ImageView imageView;
    private SeekBar seekBar;
    private ProgressBar progressBar;
    private RatingBar ratingBar;

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

        imageView = findViewById(R.id.imageView);
        seekBar = findViewById(R.id.seekBar);
        progressBar = findViewById(R.id.progressBar);
        ratingBar = findViewById(R.id.ratingBar);

        seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                imageView.setAlpha((float) progress / 255);
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {}

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {}
        });

        ratingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                Toast.makeText(MainActivity.this, "Rating: " + rating, Toast.LENGTH_SHORT).show();
            }
        });
    }
}

运行效果：
