In Android, the progress value can be set using the setProgress() method of SeekBar.

Firstly, define SeekBar in the layout file.

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

Then, locate the SeekBar in the Java code and set the progress value.

SeekBar seekBar = findViewById(R.id.seekBar);
seekBar.setProgress(50); // 设置进度值为50

Please note that the progress value of SeekBar ranges from 0 to the maximum value of SeekBar, which is 100 by default. If you need to modify the maximum value, you can use the setMax() method.

seekBar.setMax(200); // 设置最大值为200

To obtain the current progress value of a SeekBar, you can use the getProgress() method.

int progress = seekBar.getProgress(); // 获取当前进度值
