Not able to capture HTML from the browser for Android

I am trying to capture HTML code response from browser. I have created a browser and trying to capture HTML content and print in logcat.
I am getting following error message in logcat:

Starting from API level JELLY_BEAN_MR1 and above, only methods explicitly marked with the #JavascriptInterface annotation are available to the Javascript code.
You just need to add this above your showHTML method e.g:
class JavaScriptInterface{
#JavascriptInterface
public void showHTML(String html) {
m_nHTMLSize = 0;
if (html !=null) {
//int i = html.lastIndexOf(""); //search for something in the text
m_nHTMLSize = html.length();
Log.d(LOG_TAG, "HTML content is: "+html+"\nSize:"+m_nHTMLSize+" bytes");
}
}
}
Also need to remove window from you JS call:
m_web.loadUrl("javascript:window.HTMLOUT.showHTML('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>');");
to
m_web.loadUrl("javascript:HTMLOUT.showHTML('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>');");

get value from edit text within a loop

I have a question, as I can get all the data that has been inserted into the edit text? the edit text is on a loop, I need a way to get those values ​​and work with them, try using an array but I get errors. could help me? any idea? Help!
package com.example.test;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
public class MainActivity extends Activity {
public static final String TAG = MainActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText count = (EditText) findViewById(R.id.count);
final Button generate = (Button) findViewById(R.id.generate);
final LinearLayout container = (LinearLayout) findViewById(R.id.container);
generate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int numberOfControlsToGenerate = 0;
try {
numberOfControlsToGenerate = Integer.parseInt(count.getText().toString().trim());
} catch (NumberFormatException e) {
Log.e(TAG, e.getMessage(), e);
}
if (numberOfControlsToGenerate > 0) {
if (container.getChildCount() > 0) {
container.removeAllViews();
}
for (int counter = 0; counter < numberOfControlsToGenerate; counter++) {
addEditText(container);
}
}
}
});
}
private void addEditText(LinearLayout container) {
final LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
EditText editTextToAdd = new EditText(this);
editTextToAdd.setLayoutParams(params);
container.addView(editTextToAdd);
}
}

You can create multiple edittext by using array.
public class MainActivity extends Activity{
EditText[] sample_et;
int numberOfControlsToGenerate = 10;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
LinearLayout root_layout = (LinearLayout)findViewById(R.id.root);
sample_et = new EditText[numberOfControlsToGenerate];
//numberOfControlsToGenerate is decleres statically you can get the count from edit text
for(int i = 0; i < count; i++ ){
sample_et[i] = new EditText(this);
root_layout.addView(sample_et[i]);
}
}
}

Add setTag when you create dynamic EditText
add line in addEditText(LinearLayout container) method
private void addEditText(LinearLayout container) {
final LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
EditText editTextToAdd = new EditText(this);
editTextToAdd.setLayoutParams(params);
editTextToAdd.setTag(editTextToAdd); //Add this Line
container.addView(editTextToAdd);
}
Write code onClick listener on any Button
getvalue.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
for (int i = 0; i < container.getChildCount(); i++) {
if(container.getChildAt(i) instanceof EditText) {
EditText et = (EditText) container.getChildAt(i).getTag();
if(et != null) {
Log.i("<Tag Name>", et.getText().toString());
}
}
}
}
});

making press effect for button in android

i've created an android application which creates 50 button dynamically,which works perfectly, but the problem is when i put some background color for these buttons dynamically the press effect of the buttons is being lost
can anyone please tell me some solution for retaining the press effect of the button click
my code is as given below
my Android Platform is 2.3.3
import android.app.Activity;
import android.os.Bundle;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.LinearLayout;
public class MyMain extends Activity {
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.mymain);
createCalender();
}
public void createCalender()
{
LinearLayout layoutVertical = (LinearLayout) findViewById(R.id.liVLayout);
LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT, 1.0f);
param.setMargins(10, 10, 10, 10);
LinearLayout rowLayout=null;
Button[][] buttons = new Button[10][5];
int count=51;
int tab=1;
for (int i = 0; i<10; i++)
{
if(count%5==1)
{
rowLayout = new LinearLayout(this);
rowLayout.setBackgroundColor(Color.BLACK);
rowLayout.setWeightSum(5);
layoutVertical.addView(rowLayout,param);
count=count-5;
}
for(int j=0;j<5;j++)
{
buttons[i][j]=new Button(this);
buttons[i][j].setText(""+tab);
buttons[i][j].setHeight(55);
buttons[i][j].setWidth(80);
buttons[i][j].setTextColor(Color.BLACK);
buttons[i][j].setBackgroundColor(Color.GREEN);
tab++;
rowLayout.addView(buttons[i][j],param);
}
}
}
}

After buttons[i][j].setBackgroundColor(Color.GREEN);
buttons[i][j].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
v.setBackgroundColor(Color.GRAY); // Choose whichever color
new Handler().postDelayed(new Runnable() {
public void run() {
v.setBackgroundColor(Color.GREEN);
// Button Click Code Here
}
}, 100L); // Change this value to whatever is suitable
}
});

Android ObserveableScrollView to load more (loading issue)

I am fetching information from the website in JSON Format and displaying that info into my app using AsynTask. The Problem is that on On First time my Progress dialog shows well and hide after loading contents into app. But When i use Scroll-view to load more then progress dialog appears and hide after loading immediately at the same time progress dialog opens again and not hiding and Scroll-View loads data one more time in the background.I want only one time to load data after each using Scroll-View to load more. Progress Dialog is not hiding and It keeps running my app. I am struck at this point.
Basically i noticed that My Scroll-View indicator collide two times on the bottom due to this scroll-View trigger two times. How can i stop it and restrict this only one time after each scrolling.
And one more thing wanna share that everything is working awesome in Froyo 2.2 and not working in 2.3 to 4.2. Kindly help me on this. Thanks in advance.

On click Listener called twice

I know this is easy but i m just not able to debug it.
I am dynamically creating 3 LinearLayouts and adding them to a scroll View . I am adding a Button "ins" to the top of 3 linearlayout.
The problem is that on clicking the ins Button , its on clicklistener is being called 3 times .
code:
package com.integrated.mpr;
import android.app.Activity;
import android.app.Dialog;
import android.util.Log;
import android.util.TypedValue;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.ScrollView;
import android.widget.TextView;
public class Page1 extends Activity implements OnClickListener{
static int pos = new Choose().n;
static String partname;
int i;
int[][] id = new int[pos][5];
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
int p =0;
for(int i =0;i<3;i++){
for(int j =0;j<5;j++){
p++;
}
}
ScrollView sv = new ScrollView(this);
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
int resid = getResources().getIdentifier("background", "drawable", getPackageName());
ll.setBackgroundResource(resid);
Button ins = new Button(this);
ins.setText("Instructions");
ins.setOnClickListener(this);
ins.setId(5000);
ll.addView(ins);
for(i =0;i<3;i++){
LinearLayout llay = new LinearLayout(this);
llay.setOrientation(LinearLayout.VERTICAL);
TextView tv = new TextView(this);
tv.setText("enter the " +(i+1)+" position name");
EditText et = new EditText(this);
et.setId(id[i][0]);
Button starta = new Button(this);
starta.setText("Record 1");
starta.setId(id[i][1]);
starta.setOnClickListener(this);
Button startb = new Button(this);
startb.setText("Record 2");
startb.setId(id[i][2]);
startb.setOnClickListener(this);
Button startc = new Button(this);
startc.setText("Record 3");
startc.setId(id[i][3]);
startc.setOnClickListener(this);
Button stop = new Button(this);
stop.setText("Submit");
stop.setId(id[i][4]);
stop.setOnClickListener(this);
TextView tv1 = new TextView(this);
tv1.setVisibility(llay.INVISIBLE);
llay.addView(tv);
llay.addView(et);
llay.addView(starta);
llay.addView(startb);
llay.addView(startc);
llay.addView(stop);
llay.addView(tv1);
ll.addView(llay);
}
Button bcon = new Button(this);
bcon.setText("Continue");
bcon.setId(10000);
bcon.setOnClickListener(this);
ll.addView(bcon);
sv.addView(ll);
this.setContentView(sv);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v.getId()==5000){
Log.d("ins", "called");
Context mContext = Page1.this;
Dialog dialog = new Dialog(mContext);
dialog.setTitle("Instructions");
dialog.setContentView(R.layout.instructiondialog);
dialog.show();
}
}
}
}
I know definitely , there is some problem in the code of OnCreate but what it is ? Help please
Can anyone further explain how to set the button aligned o the right of screen , that is how to set its layout gravity?

I am not sure about what exactly you want to achieve.but you can set the flag.if flag value is 1 then only process onClick else not.
Below snippet will help you.
Yes but you will have to somehow reset that flag to 1.
#Override
public void onClick(View v)
{
// TODO Auto-generated method stub
if(v.getId()==5000)
{
if(flag)
{
Log.d("ins", "called");
Context mContext = Page1.this;
Dialog dialog = new Dialog(mContext);
dialog.setTitle("Instructions");
dialog.setContentView(R.layout.instructiondialog);
dialog.show();
}
flag=0;
}
}

You can also call button click event like this
Button ins = new Button(this);
ins.setText("Instructions");
ins.setOnClickListener(this);
ins.setId(5000);
ins.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
// TODO Auto-generated method stub
Context mContext = Page1.this;
Dialog dialog = new Dialog(mContext);
dialog.setTitle("Instructions");
dialog.setContentView(R.layout.instructiondialog);
dialog.show();
}
});
