<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@android:id/background">
        <shape>
            <corners android:radius="2dp" />
            <gradient

设置背景

 <item android:id="@android:id/progress">
设置进度

MainActivity

public class MainActivity extends AppCompatActivity {

    private ProgressBar mPb;
    private SeekBar mSb;

    @RequiresApi(api = Build.VERSION_CODES.N)
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mPb = ((ProgressBar) this.findViewById(R.id.pb));
        mSb = ((SeekBar) this.findViewById(R.id.sb));

        mSb.setProgress(50);
        mPb.setProgress(50, true);

    }


}

 可以满足一般的进度条设置。
