推荐答案
您可以将宽度的 IMG 到 100％的属性并没有设置height属性
you can set width attribute of img to 100% and don't set height attribute
<body >
<img id="resizeImage" src="you_image.png" width="100%" alt="" />
</body>
编辑： 其实我也有同样的问题。但是我仍然在等待正确的答案。

虽然我已成功一些如何这个问题，一招用管理的高度和宽度设备的。并使用 wv.setInitialScale（185）; ByDefault缩放将在左上角
though i have managed some how this Problem with a Trick by managing height and Width of Device. and Using wv.setInitialScale(185); ByDefault the Zoom will be in Top Left Corner.
我已经把我下面的code。
i have put my code below.
WindowManager mWinMgr;
public static int displayWidth = 0, displayHeight = 0;
@Override
protected void onCreate(Bundle icicle) {
// TODO Auto-generated method stub
super.onCreate(icicle);
// this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
// this.setProgressBarVisibility(true);
mWinMgr = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
displayWidth = mWinMgr.getDefaultDisplay().getWidth();
displayHeight = mWinMgr.getDefaultDisplay().getHeight();
setContentView(R.layout.view_my_poops);
try {
Map_Type = getIntent().getExtras().getString("MAP_TYPE");
} catch (Exception e) {
}
Log.i(TAG, "MAP TYPE" + Map_Type);
}
@SuppressLint("SetJavaScriptEnabled")
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
WebView wv;
wv = (WebView) findViewById(R.id.webview_MyPoops);
wv.getSettings().setJavaScriptEnabled(true);
// this.setProgressBarVisibility(true);
if (displayWidth >= 552 && displayHeight >= 976 || displayWidth >= 976
&& displayHeight >= 552) {
wv.setInitialScale(185);
} else {
// wv.setInitialScale(150);
}
// wv.setInitialScale(30);
URL = "YOUR_URL";
Log.i(TAG, "Loading URL" + URL);
final Activity activity = ViewMyPoop.this;
wv.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// TODO Auto-generated method stub
// Log.i(TAG, "Inside OnProgress Changed" + URL);
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if (progress == 100)
activity.setTitle("My title");
}
});
wv.loadUrl(URL);
wv.setWebViewClient(new WebViewClient());
}
