我想知道为什么在我将操作系统版本从 2.3.6 更新到 4.0.3 后我不能在我的 WebView 中播放 youtube.com，下面是我的代码
布局
<WebView
android:id="@+id/video"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="0.55"
android:scrollbars="none"
/>
显现
在这里我想添加 "android:hardwareAccelerated="true" 但不允许在 eclip 中添加这一行:(
<application
android:icon="@drawable/ic_perry"
android:label="@string/app_name"
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >
<activity
android:name=".MeasSokSopheaActivity"
android:label="@string/app_name"
android:screenOrientation="nosensor" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".video" />
</application>
活动
public class video extends Activity {
private WebView mWebView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.video);
if(!haveNetworkConnection())
{
AlertDialog alertDialog = new AlertDialog.Builder(video.this).create();
alertDialog.setTitle("Connection Error!");
alertDialog.setMessage("Please connected to the internet in order to use this apps.");
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
//here you can add functions
} });
alertDialog.setIcon(android.R.drawable.ic_dialog_info);
alertDialog.show();
}
