如何在 android 设备中使用本机指纹扫描仪 UI？

Question

要求：如何为屏幕传感器 android 设备（如三星 s10 plus）使用本机指纹扫描仪 UI。

指纹认证的工作流程是可以理解的。但是是否有任何方法或库可用于获取本机指纹扫描仪UI？

Answer 1

解决方案是创建一个自定义 UI 并替换它，以便它对所有设备都相同 UI

public class MyFingerPrintDialog extends BottomSheetDialog implements 
View.OnClickListener {

private Context context;

private Button btnCancel;
private TextView itemTitle;

private BiometricCallback biometricCallback;

public MyFingerPrintDialog(@NonNull Context context) {
    super(context, R.style.BottomSheetDialogTheme);
    this.context = context.getApplicationContext();
    setDialogView();
}

public MyFingerPrintDialog(@NonNull Context context, BiometricCallback biometricCallback) {
    super(context, R.style.BottomSheetDialogTheme);
    this.context = context.getApplicationContext();
    this.biometricCallback = biometricCallback;
    setDialogView();
}

public MyFingerPrintDialog(@NonNull Context context, int theme) {
    super(context, theme);
}

protected MyFingerPrintDialog(@NonNull Context context, boolean cancelable, OnCancelListener cancelListener) {
    super(context, cancelable, cancelListener);
}

private void setDialogView() {
    View bottomSheetView = getLayoutInflater().inflate(R.layout.view_bottom_sheet, null);
    setContentView(bottomSheetView);

    btnCancel = findViewById(R.id.btn_cancel);
    btnCancel.setOnClickListener(this);

    itemTitle = findViewById(R.id.item_title);
}

BiometricCallback

public interface BiometricCallback {

void onAuthenticationFailed();

void onAuthenticationCancelled();

void onAuthenticationSuccessful();
}
