The Android ProgressBar component is used to display the progress of a task. It can be added directly in the layout file or dynamically through code.

Here are some common methods using the ProgressBar component:

  1. Add a ProgressBar component in the layout file.
<ProgressBar
    android:id="@+id/progressBar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    style="?android:attr/progressBarStyleHorizontal" />
  1. Accessing a ProgressBar instance within the code and setting the progress:
ProgressBar progressBar = findViewById(R.id.progressBar);
progressBar.setProgress(50); // 设置进度为50%
  1. Customize the style and color of the ProgressBar.
progressBar.setProgressDrawable(ContextCompat.getDrawable(this, R.drawable.custom_progress_bar));
progressBar.getProgressDrawable().setColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);
  1. Set the maximum progress value and progress value for the ProgressBar.
progressBar.setMax(100); // 设置最大进度值为100
progressBar.setProgress(75); // 设置当前进度为75%
  1. Set the ProgressBar to indeterminate mode.
progressBar.setIndeterminate(true);

These are some common methods for using the Android ProgressBar component which can be further customized and adjusted according to specific needs.
