如何在加载内容后将webview的内容缩放到特定的比例?(我不想重新加载内容。)
我正在开发android 2.3和更高版本。

最佳答案

解决方案1:这里我们按百分比设置缩放级别这意味着当页面准备好时,getscale将返回5.2f:

mView.setWebViewClient(new WebViewClient() {
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        view.setInitialScale(520);

        super.onPageStarted(view, url, favicon);
    }

解决方案2:此方法不是100%精确的,因为它将刻度舍入为int值:
private WebView mView;
private Handler mZoomHandler = new Handler();
private Runnable mZoomRunnable = new Runnable() {

    @Override
    public void run() {
        if ((int) mView.getScale() < WANTED_SCALE) {
            mView.zoomIn();
            mZoomHandler.postDelayed(this, 10);
        } else if ((int) mView.getScale() > WANTED_SCALE) {
            mView.zoomOut();
            mZoomHandler.postDelayed(this, 10);
        }
    }
};

mView.getSettings().setSupportZoom(true);
mView.setWebViewClient(new WebViewClient() {
    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        mZoomRunnable.run();
    }
});
