getSettings().setBuiltInZoomControls(false);

use the above line of code to remove the zoom buttons.

使用上面的代码行删除缩放按钮。

On API >= 11, you can use:

在 API >= 11 上，您可以使用：

webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setDisplayZoomControls(false);

Updated:::If you want have zoom in/out without zoom controls then use the below code(copied from here)

更新::：如果您想在没有缩放控件的情况下放大/缩小，请使用以下代码（从此处复制）

public class Main extends Activity {
? private WebView myWebView;
? private static final FrameLayout.LayoutParams ZOOM_PARAMS =
new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
Gravity.BOTTOM);

? @Override
? protected void onCreate(Bundle savedInstanceState) {
? ? super.onCreate(savedInstanceState);
? ? setContentView(R.layout.webview);
    myWebView = (WebView)findViewById(R.id.webView);

? ? FrameLayout mContentView = (FrameLayout) getWindow().
? ? getDecorView().findViewById(android.R.id.content);
? ? final View zoom = myWebView.getZoomControls();
? ? mContentView.addView(zoom, ZOOM_PARAMS);
? ? zoom.setVisibility(View.GONE);

? ? myWebView.loadUrl("http://www.almondmendoza.com");
? }
}

Change this on your AndroidManifest:

在您的 AndroidManifest 上更改此设置：

    android:minSdkVersion="8"

to this:

对此：

    android:minSdkVersion="11"

than use this in your web view settings:

而不是在您的网络视图设置中使用它：

getSettings().setBuiltInZoomControls(true);
    getSettings().setDisplayZoomControls(false);

If you want to disable only zoom controls use this: webView.getSettings().setDisplayZoomControls(false);

如果您只想禁用缩放控件，请使用以下命令： webView.getSettings().setDisplayZoomControls(false);

zoom buttons can be removed by implementing your own custom webview, and using reflection to get the built in zoom controls and making them invisible for API below 11 (Honeycomb). The code is as thus works for all APIs upto android nougat;

缩放按钮可以通过实现你自己的自定义 webview 来移除，并使用反射来获取内置的缩放控件并使它们对于低于 11 (Honeycomb) 的 API 不可见。代码因此适用于所有 API，直到 android nougat；

public class CustomWebView extends WebView{

    private ZoomButtonsController zoom_controll = null;

    public CustomWebView(Context context) {
        this(context, null);
    }

    public CustomWebView(Context context, AttributeSet attrs) {
        this(context, attrs, android.R.attr.webViewStyle);
    }

    public CustomWebView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initWebSettings();
    }

    @SuppressLint("NewApi")
    private void initWebSettings() {
        WebSettings webSettings = getSettings();

        webSettings.setSupportZoom(true);
        webSettings.setBuiltInZoomControls(true);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            webSettings.setAllowContentAccess(true);
            webSettings.setDisplayZoomControls(false);

        } else {
            try {
                Class webview = Class.forName("android.webkit.WebView");
                Method method = webview.getMethod("getZoomButtonsController");
                zoom_controll = (ZoomButtonsController) method.invoke(this, null);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }


    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if(zoom_controll != null)
            zoom_controll.getZoomControls().setVisibility(View.GONE);
        return super.onTouchEvent(event);
    }

}

Here is a solution:

这是一个解决方案：

    if (ev.getAction() == MotionEvent.ACTION_DOWN ||
        ev.getAction() == MotionEvent.ACTION_POINTER_DOWN ||
        ev.getAction() == MotionEvent.ACTION_POINTER_1_DOWN ||
        ev.getAction() == MotionEvent.ACTION_POINTER_2_DOWN ||
        ev.getAction() == MotionEvent.ACTION_POINTER_3_DOWN) {
    if (multiTouchZoom && !buttonsZoom) {
        if (ev.getPointerCount() > 1) {
            getSettings().setBuiltInZoomControls(true);
            getSettings().setSupportZoom(true);
        } else {
            getSettings().setBuiltInZoomControls(false);
            getSettings().setSupportZoom(false);
        }
    }
}

if (!multiTouchZoom && buttonsZoom) {
    if (getPointerCount(ev) > 1) {
        return true;
    }
}

In your case multiTouchZoomis true and buttonsZoomis false.

在你的情况下multiTouchZoom是真的，buttonsZoom是假的。

I found it here enable/disable zoom in Android WebViewand it's worked for me.

我在这里发现它在 Android WebView 中启用/禁用缩放，它对我有用。
