Webview get focus automatically when removing URL from Edit Text

I have one Edit Text, 5 buttons and a Webview. Webview load url when user type url in edit text and tap Go button or hit Enter on soft keyboard.
I have three problems here.
1-WebView loads website for example "www.google.com" but soft keyboard does not hide itself. I want to hide it like other browser do.
2-When user open a specific url and then try to remove it from Edit Text to open a different url, webview start loading that incomplete url and get focus automatically on every letter removing. For example user loads "www.google.com" then he try to remove url from end and as he remove "m", webview try to load "www.google.co" then edit text is out of focus and webview stole focus from it then user have to tap in edit text again to remove url but it tries to load after every letter removing. I need Webview to load url only when user tap on Go button or hit Enter on soft keyboard.
Update (forgot to add third problem, here it is)
3-Where can i check when WebView CanGoBack and CanGoForward because i want to set visibility of Back and Forward buttons to false at startup and enabled these two buttons while they CanGoBack and CanGoForward. Where should i put my piece of code to check these conditions?
I hope you guys can understand what i am trying to say. Sorry for my poor english.
Here is my xml code.

Here is my java code.
public class MainActivity extends AppCompatActivity implements View.OnClickListener {

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wb = (WebView) findViewById(R.id.wb);
wb.getSettings().setJavaScriptEnabled(true);
wb.getSettings().setUseWideViewPort(true);
wb.getSettings().setLoadWithOverviewMode(true);
wb.setWebViewClient(new ourClient());
etUrl = (EditText) findViewById(R.id.etUrl);
btnGo = (Button) findViewById(R.id.btnGo);
btnBack = (Button) findViewById(R.id.btnBack);
btnForward = (Button) findViewById(R.id.btnForward);

btnReload = (Button) findViewById(R.id.btnReload);
btnGo.setOnClickListener(this);
btnReload.setOnClickListener(this);
btnBack.setOnClickListener(this);
btnForward.setOnClickListener(this);
btnClear.setOnClickListener(this);
etUrl.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View view, int i, KeyEvent keyEvent) {
if (keyEvent.getAction()==KeyEvent.ACTION_DOWN && i==KeyEvent.KEYCODE_ENTER) {
return true;
}
load();
return false;
}
});
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnGo:
load();
break;
case R.id.btnBack:
if (wb.canGoBack())
wb.goBack();
break;
case R.id.btnForward:
if (wb.canGoForward())
wb.goForward();
break;
case R.id.btnReload:
wb.reload();
break;
case R.id.btnClear:
wb.clearHistory();
break;
}
}
public void load(){
url = etUrl.getText().toString();
if (!url.startsWith("http://")) {
url = "http://" + url;
}
try {
wb.loadUrl(url);
wb.requestFocus();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), " " + e, Toast.LENGTH_LONG).show();
}
}
}

use this method to hide the keyboard:
public static void hideSoftKeyboard(Activity context) {
InputMethodManager inputManager = (InputMethodManager) context
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (inputManager != null)
inputManager.hideSoftInputFromWindow(context.getWindow()
.getDecorView().getApplicationWindowToken(), 0);
context.getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}
call it in your load() method like:
hideSoftKeyboard(MainActivity.this);
For your second question you need to call your method inside the condition like:
etUrl.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View view, int i, KeyEvent keyEvent) {
if ((keyEvent.getAction()==KeyEvent.ACTION_DOWN) && (i==KeyEvent.KEYCODE_ENTER)){
load(); //add it here
return true;
}
return false;
}
});
EDIT
For the webview go back feature: override onKeyDown in your activity and check condition like:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// Check if the key event was the Back button and if there's history
if ((keyCode == KeyEvent.KEYCODE_BACK) && wb.canGoBack()) {
wb.goBack();
//show your back button here
return true;
}
// If it wasn't the Back key or there's no web page history, bubble up to the default
// system behavior (probably exit the activity)
//show other buttons
return super.onKeyDown(keyCode, event);
}
You can add the check in your onResume() and load() also and show your button accordingly..
#Override
protected void onResume() {
super.onResume();
if(wb.canGoBack()){
//show back button}
else{
//other button
}
}

Keep current page rendered until the next page is loaded

I have a simple app that is based on WebView.loadUrl("http://www.example.com").
When a user clicks on a URL, the default behavior is to immediately show a blank page, wait until the page is loaded, and then show this page.
I managed to show a splash screen in lieu of the blank page. However, is it possible to keep the current page rendered instead, and render the next page only when it is fully loaded?

This is, I feel, a hacky solution. I offer it as a temporary fix until someone posts the "real" way to do this.
MainActivity class:
public class MainActivity extends Activity
{
WebView webView1, webView2;
EditText editText;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
editText = (EditText) findViewById(R.id.edit_url);
webView1 = (WebView) findViewById(R.id.webView_1);
webView2 = (WebView) findViewById(R.id.webView_2);
webView1.setWebViewClient(client);
webView2.setWebViewClient(client);
webView1.loadUrl(editText.getText().toString());
}
private WebViewClient client = new WebViewClient()
{
public void onPageFinished(WebView webView, String url)
{
if (webView == webView1)
webView2.setVisibility(View.GONE);
else
webView1.setVisibility(View.GONE);
webView.setVisibility(View.VISIBLE);
Toast.makeText(MainActivity.this, "WebView " + (webView == webView1 ? "One" : "Two") + " is showing", 0).show();
}
};
private void loadUrl(String url)
{
if (webView1.getVisibility() == View.GONE)
webView1.loadUrl(url);
else
webView2.loadUrl(url);
}
public void onClick(View v)
{
loadUrl(editText.getText().toString());
}
}

WebView causes application restart - Fatal signal 11 (SIGSEGV)

I have an activity that displays web pages. On some phones (e.g, Huawei Ascend) , this activity crashes in a way that causes the application to restart, but doesn't cause the usual android error popup for reporting. (Other phones (e.g. Nexus) never crash at all.) It does appear to always crash while a web page is loading, but not at any particular point e.g. sometimes at shoulOverrideUrlLoading, sometimes during onPageStarted or onPageFinished.
I think the WebView is causing this--
08-29 21:08:22.577: A/libc(957): Fatal signal 11 (SIGSEGV) at 0x00000008 (code=1), thread 957
--but I can't work out why.
Here's the activity:
public class WebDisplay extends Activity

private String sentUrl = "";
public WebView myWebView;
public ProgressBar spinner;

// WebView displays default to showing things in exact pixel size at 100%
// resolution, meaning it generally opens on a zoomed in portion of the
// top left of the web page and refuses to let you zoom out, so we have

myWebView.getSettings().setLoadWithOverviewMode(true);
myWebView.getSettings().setUseWideViewPort(true);
myWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
// By default, there is no javascript support or zoom controls, so
// turn both of those on.
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setSupportZoom(true);

// We want links to continue opening inside the app.
myWebView.setWebViewClient(new WebViewClient() {

}
});
// Try to get YouTube videos working.
myWebView.setWebChromeClient(new WebChromeClient() {

// So the user doesn't have to back through their entire history to get
// back to the app, we provide a "done browsing" button.
Button doneButton = (Button) findViewById(R.id.doneButton);
doneButton.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v)
{
finish();
}
});
ImageButton backButton = (ImageButton) findViewById(R.id.webBackButton);
backButton.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View arg0)
{
myWebView.goBack();

});
ImageButton fwdButton = (ImageButton) findViewById(R.id.webForwardButton);
fwdButton.setOnClickListener(new OnClickListener(){
#Override

{
myWebView.goForward();
}
});
ImageButton refreshButton = (ImageButton) findViewById(R.id.refreshButton);
refreshButton.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View arg0)
{
myWebView.reload();
}
});
myWebView.loadUrl(sentUrl);
}
#Override
protected void onSaveInstanceState(Bundle outState)
{
super.onSaveInstanceState(outState);
// Save the state of the WebView
myWebView.saveState(outState);
}
#Override

{
super.onRestoreInstanceState(savedInstanceState);
// Restore the state of the WebView

}

ETA: Turning hardware acceleration off like this
myWebView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
seems to stop the SIGSEV thing, but also stops YouTube videos playing (I still have audio, but no image).

make sure the WebView is the first element of the RelativeLayout.
or don't use RelativeLayout, just try LinearLayout.
or remove the attributes
android:layout_alignParentTop="true"
android:layout_above="#id/webNavBar"
of WebView

webSettings.setJavaScriptEnabled(true);
Settings above causes "Fatal signal 11 (SIGSEGV)" error for some sites using java script. I reproduced this error on Samsung Galaxy Tab 3 And Galaxy tab 3 lite. Android version is 4.4.2 for both devices.
If I remove "setJavaScriptEnabled" function, it is working fine.

Android drag and drop in tab view stops working after tab index changes

Ok, I've implemented a android datagrid that amongst other things, lets you drag and drop columns around. This functionality works beautifully (better than I expected).
I noticed recently that if the grids were placed in tabcontents... it seems like zindex isnt taken into account (even though my ACTION_DRAG_STARTED will return false for column headers further back in the z-index, I still see those column headers responding to some events (like ACTION_DRAG_EXITED).
Attempting to have a controlled environment, I went ahead and built a stand alone project that demonstrates this problem.
I am hoping its something simple I missed, or perhaps ideas on how to work around it. Pretty simple to reproduce... run project, drag buttons around with long press... change tabs, drag those around, change back to first tab, drag around. It should start drag process, but as soon as you drag out of the control you were just in, you see "Reporting drop result:false".
Any pointers would be greatly appreciated... I suspect the underlying views are cancelling the drag event.

How to change icon on the SlidingDrawer handle when clicked

Im trying to change the icon on the handle when i try to open the slidingdrawer.
When I extract the handle from the view and sets the onclicklistener or ontouchlistener it seems to never get trigget.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SlidingDrawer drawer = (SlidingDrawer)findViewById(R.id.drawer_landscape);
ImageView handle = (ImageView)findViewById(R.id.handle_l);
handle.setFocusable(true);
handle.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.i("test","onClick");
}
});
}
And my XML
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/base_frame_layout"
android:layout_gravity="bottom"
>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello"
/>
</LinearLayout>
<SlidingDrawer
android:id="#+id/drawer_landscape"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:handle="#+id/handle_l"
android:content="#+id/content"
android:orientation="vertical"
android:visibility="visible"
>
<ImageView
android:id="#+id/handle_l"
android:layout_height="50px"
android:layout_width="64px"
android:padding="0px"
android:src="#drawable/icon"
/>
<TextView
android:id="#+id/content"
android:text="content"
android:layout_height="50px"
android:layout_width="64px"
/>
</SlidingDrawer>
</FrameLayout>
I was hoping this code should log "onClick" message, but it doesn't.
Any ideas?

I found it, it was pritty easy... I just need to setOnDrawerScrollListener on my drawer.
than implement the 2 methods onScrollEnded and onScrollStarted.
mSlidingDrawer.setOnDrawerScrollListener(new OnDrawerScrollListener(){
#Override
public void onScrollEnded() {
// TODO Auto-generated method stub
Log.i("ddd","onScrollEnded slider");
slider_animation.reverseTransition(HANDLE_ANIMATION_SPEED);
}
#Override
public void onScrollStarted() {
// TODO Auto-generated method stub
Log.i("ddd","onScrollStarted slider");
slider_animation.startTransition(HANDLE_ANIMATION_SPEED);
}
});
I rather use an animation on the handle instead of changing the Image bacause of the flickering.

I found it for along time , but now it is completed about it .
It is the best way for Change Image Handle when you click to view SlidingDrawer.
It have 2 Method that we use in code below.
final SlidingDrawer drawer = (SlidingDrawer)findViewById(R.id.slidingDrawer);
drawer.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() {
#Override
public void onDrawerOpened() {
arr.setImageResource(R.drawable.arrowdown);
}
});
drawer.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {
#Override
public void onDrawerClosed() {
arr.setImageResource(R.drawable.arrowup);
}
});
