本篇常用的View如图中所示：

xml布局代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

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

        <ProgressBar
            android:id="@+id/pb_progress_load"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="请稍候" />
    </LinearLayout>

    <ProgressBar
        android:id="@+id/pb_progress_loading"
        style="?android:progressBarStyleHorizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <SeekBar
        android:id="@+id/sb_progress_loading"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="1.随便写凑字数的\n2.GODVGODVGODV"/>
</LinearLayout>

 java代码

public class ProgressActivity extends AppCompatActivity {
    private ProgressBar pb_progress_load;
    private ProgressBar pb_progress_loading;
    private SeekBar sb_progress_loading;

    private SeekBar.OnSeekBarChangeListener onSeekBarChangeListener = new SeekBar.OnSeekBarChangeListener() {
        @Override
        public void onProgressChanged(SeekBar seekBar, int i, boolean b) {

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            pb_progress_loading.setProgress(seekBar.getProgress());
            if (seekBar.getProgress() == seekBar.getMax()) {
                pb_progress_load.setVisibility(View.GONE);
            } else {
                pb_progress_load.setVisibility(View.VISIBLE);
            }
        }
    };


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_progress);
        pb_progress_load = findViewById(R.id.pb_progress_load);
        pb_progress_loading = findViewById(R.id.pb_progress_loading);
        sb_progress_loading = findViewById(R.id.sb_progress_loading);

        sb_progress_loading.setOnSeekBarChangeListener(onSeekBarChangeListener);
