Android 滑块验证

先上图看看实现效果

1.在 app 的 build.gradle 添加依赖

implementation 'com.luozm.captcha:captcha:1.1.2' 

2.将 Captcha 添加至布局文件

 <com.luozm.captcha.Captcha         android:id="@+id/captCha"         android:layout_centerInParent="true"         android:layout_width="match_parent"         android:layout_height="265dp"         android:layout_marginRight="10dp"         android:layout_marginLeft="10dp"         app:mode="mode_bar"         app:src="@drawable/validate"         app:blockSize="50dp"         android:scaleType="centerCrop"         app:max_fail_count="4"/> 

3.添加 Java 代码

    public void showw(String advPic) {          Context context = MainActivity.this;         diaa = new Dialog(context, R.style.edit_AlertDialog_style);         diaa.setContentView(R.layout.item_pict);          captcha = diaa.findViewById(R.id.captCha);         final Button btn_mode = diaa.findViewById(R.id.btn_mode);         final Captcha captcha = diaa.findViewById(R.id.captCha);         ImageView cuowu = diaa.findViewById(R.id.im_cuowu);         // Glide.with(getApplication()).load(advPic).into(captcha );         captcha.setBitmap(advPic);          btn_mode.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                 if (captcha.getMode() == Captcha.MODE_BAR) {                     captcha.setMode(Captcha.MODE_NONBAR);                     btn_mode.setText("滑动条模式");                 } else {                     captcha.setMode(Captcha.MODE_BAR);                     btn_mode.setText("无滑动条模式");                 }             }         });          cuowu.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                 diaa.dismiss();                 itData(mLongitude, mLatitude);             }         });          captcha.setCaptchaListener(new Captcha.CaptchaListener() {             @Override             public String onAccess(long time) {                 Toast.makeText(MainActivity.this, "验证成功", Toast.LENGTH_SHORT).show();                   diaa.dismiss();                 diaa.setCanceledOnTouchOutside(true);                 return "验证通过";              }              @Override             public String onFailed(int count) {                 Toast.makeText(MainActivity.this, "验证失败,失败次数" + count, Toast.LENGTH_SHORT).show();                 return "验证失败";             }              @Override             public String onMaxFailed() {                 Toast.makeText(MainActivity.this, "验证超过次数，你的帐号被封锁", Toast.LENGTH_SHORT).show();                 return "可以走了";             }          });          diaa.show();          diaa.setCanceledOnTouchOutside(true);           Window w = diaa.getWindow();         WindowManager.LayoutParams lp = w.getAttributes();         lp.x = 0;         lp.y = 40;         diaa.onWindowAttributesChanged(lp);       }
