app直播源码，Android 滑动拼图验证码控件

1.视图布局文件：activity_main.xml。

<?xml version="1.0" encoding="utf-8"?><br><android.support.constraint.ConstraintLayout<br>    xmlns:android="http://schemas.android.com/apk/res/android"<br>    xmlns:app="http://schemas.android.com/apk/res-auto"<br>    xmlns:tools="http://schemas.android.com/tools"<br>    android:layout_width="match_parent"<br>    android:layout_height="match_parent"<br>    tools:context="com.slideimage.MainActivity"><br>    <com.slideimage.SlideImageView<br>        android:id="@+id/slide_image_view"<br>        android:layout_width="240dp"<br>        android:layout_height="150dp"<br>        android:layout_marginTop="50dp"<br>        app:layout_constraintTop_toTopOf="parent"<br>        app:layout_constraintLeft_toLeftOf="parent"<br>        app:layout_constraintRight_toRightOf="parent"/><br>    <View<br>        android:id="@+id/flash_view"<br>        android:layout_width="wrap_content"<br>        android:layout_height="wrap_content"<br>        android:visibility="invisible"<br>        app:layout_constraintLeft_toLeftOf="@id/slide_image_view"<br>        app:layout_constraintRight_toRightOf="@id/slide_image_view"<br>        app:layout_constraintTop_toTopOf="@id/slide_image_view"<br>        app:layout_constraintBottom_toBottomOf="@id/slide_image_view"<br>        android:background="@mipmap/drag_flash"/><br>    <SeekBar<br>        android:id="@+id/seekBar1"<br>        android:layout_width="240dp"<br>        android:layout_height="wrap_content"<br>        android:layout_marginTop="220dp"<br>        app:layout_constraintTop_toTopOf="parent"<br>        app:layout_constraintLeft_toLeftOf="parent"<br>        app:layout_constraintRight_toRightOf="parent"/><br>    <TextView<br>        android:id="@+id/show_result"<br>        android:layout_width="wrap_content"<br>        android:layout_height="wrap_content"<br>        android:layout_marginTop="280dp"<br>        android:textSize="20sp"<br>        app:layout_constraintLeft_toLeftOf="parent"<br>        app:layout_constraintRight_toRightOf="parent"<br>        app:layout_constraintTop_toTopOf="parent"/><br>    <Button<br>        android:id="@+id/button1"<br>        android:layout_width="wrap_content"<br>        android:layout_height="wrap_content"<br>        android:layout_marginTop="320dp"<br>        android:text="重新初始化"<br>        app:layout_constraintTop_toTopOf="parent"<br>        app:layout_constraintLeft_toLeftOf="parent"<br>        app:layout_constraintRight_toRightOf="parent"/><br></android.support.constraint.ConstraintLayout><br> 

2.在Activity中使用滑块验证：MainActivity.java。

public class MainActivity extends AppCompatActivity {<br>    private SeekBar seekBar;<br>    private Button button1;<br>    private SlideImageView slideImageView;<br>    private TextView resultText;<br>    private View flashView;<br>    private static final int flashTime = 800;<br>    private long timeStart = 0;<br>    private float timeUsed;<br>    @SuppressLint("ClickableViewAccessibility")<br>    @Override<br>    protected void onCreate(Bundle savedInstanceState) {<br>        super.onCreate(savedInstanceState);<br>        setContentView(R.layout.activity_main);<br>        seekBar = findViewById(R.id.seekBar1);<br>        button1 = findViewById(R.id.button1);<br>        slideImageView = findViewById(R.id.slide_image_view);<br>        flashView = findViewById(R.id.flash_view);<br>        resultText = findViewById(R.id.show_result);<br>        slideImageView.setImageBitmap(BitmapFactory.decodeResource(getResources(), R.mipmap.slide_bg));<br>        seekBar.setMax(10000);<br>        seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener(){<br>            @Override<br>            public void onProgressChanged(SeekBar seekBar, int progress,<br>                                          boolean fromUser) {<br>                slideImageView.setMove(progress*0.0001);<br>            }<br>            @Override<br>            public void onStartTrackingTouch(SeekBar seekBar) {<br>                timeStart = System.currentTimeMillis();<br>            }<br>            @Override<br>            public void onStopTrackingTouch(SeekBar seekBar) {<br>            }<br>        });
