whenever i try to start the webview activity though a button it says the app has stopped

I am trying to create an app that implements the webview activity whenever you press a button but. Whenever I press it gives me an, unfortunately, message instead of going to it. Everything seems to be right and I put it through the debugger and it gave me the error "E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.time_app, PID: 7599
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.time_app/com.example.time_app.Browser}: android.view.InflateException: Binary XML file line #8: Error inflating class android.webkit.WebView".It says the problem is at line 42 in the browser.java file which is "setContentView(R.layout.activity_browser);".Ive checked all of my lines of code and it all seems right.

Clicking on EditText does absolutely nothing and cursor stays at end

How do I get it to open up the keyboard on click and change the cursor position when the user clicks within the text? I'm sure it's something simple, but I've tried setting focusable and focusableInTouchMode to true, enabled, textIsSelectable, and nothing has worked. Have also tried using the following in my code:
InputMethodManager im = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
im.showSoftInput(typeField, 0);

My activity extends AppCompatActivity, if that's important.
Once I click the back button to make the keyboard disappear, I can't make it reappear when I click inside the EditText. Another thing I can't do is move the cursor when I tap inside a String I've already written so if I messed up somewhere, I have to delete text and retype. It's just so frustrating because I have an EditText in another file that works fine and I didn't have to do anything special. The keyboard is opened when I first enter the activity, which is great.
I'm fairly new to Android development so please put things in simple terms, if possible. Thank you so much!

Try this code it may help you solve your problem...

import android.content.Context;

import android.view.View;
import android.view.inputmethod.InputMethodManager;
public class AndroidExternalFontsActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
View view = this.getCurrentFocus();
if (view != null) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInputFromInputMethod(view.getWindowToken(), 0);
}
}
}

Android EditText not editable

I have a 2 activities with edittexts on them the first activity work fine but the second activity's EditText is focused but I can't edit it nor can I click the button on it.
Also everything works in the emulator but not when I install it on the device. (The keyboard popup also does not come up in the second activity where as it does in the first activity)

I just figured to re-create the app. I dont think it is a wise decision to copy the raw files to another directory and use that.

Android onclick Buttons Sequence

I have 5 buttons every one has letter (Button "H",Button "E"Button "L"Button "L"Button "O") which make the word "HELLO". what I need is to make on click sequence to these buttons so if I click "H" first and "E" second until complete the word the app will do something, But if I click "L" first will give me some error message.
Any Idea to do this sequence?
Thanks

Just have an Array like this:
int[] tracker = new int[5];
and when you click a button, say "H", set tracker[0] = 1;
but when you click a button, say "L", check whether all the previous button values are 1. If yes, then set the corresponding tracker to 1 else, show an error message, and do not make any change to the tracker Array.
Something Like this:
onHClick{
tracker[0] = 1;
}
onEClick{
for(int i=0; i<1; i++){
if(tracker[i] == 0){
//show error message and return;
}else{
tracker[1] = 1;
return;
}
}
}

You can do something like
When activity started you just make other button Enabled = false of something like that. But make the first button Enabled. Don't make the Visible=false.
Now on click of Button "H" make enable Button "E" and so on.
So user will only have to click the button in sequence. Button can not be presses in any random manner.
Try this and let me know that it works or not.

Very Interesting and exactly same to your requirement..check once..
If you give any string other than HELLO also works better.
public class ButtonTest extends Activity
{
private String result="";
String sampleText = "HELLO";
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
int noOfBtns = sampleText.length();
LinearLayout ll = (LinearLayout)findViewById(R.id.btnlay);
final TextView tvtext = (TextView)findViewById(R.id.result);
final Button[] btns = new Button[noOfBtns];
for(int i=0;i<noOfBtns;i++)
{
btns[i] = new Button(this);
btns[i].setText(sampleText.substring(i,i+1));
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
ll.addView(btns[i], lp);
final int j = i;
btns[i].setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
System.out.println(j+" "+result.length());
if(j == result.length())
{
result = result+btns[j].getText().toString();
if(sampleText.startsWith(result))
{
tvtext.setText(result);
}
}
else
{
Toast.makeText(getApplicationContext(), "Wrong Button Pressed", Toast.LENGTH_SHORT).show();
}
}
});
}
}
}

I don't know exactly your flow but you can try this.
set Tag to each button as its Text, like this.
b.setTag("H");
and than after like this.
Button b;
String name = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String s = (String) v.getTag();
name +=s;
if( "HELLO".startsWith(name)){
<VALID>
}else{
<ERROR>
}
}
});
}
check the variable name on each button click with your original word i.e. HELLO like above.

Android speech to text using listview

The code below is used to convert speech to text on an android app. This code works when the speech button is pressed and whatever you say is transferred into text.
When the speech function closes, the the text is showing.
If you hit the speech button again, the previous text is cleared and the new text shows on the page. What i want to do is everytime i click the speak button, i want to show the word on the page.. then if i click the speak button again, i want the next word to appear under the first word in a list format.
i am looking to use listview but am struggling. here is the original code and the code i am trying to write to make it a listview. can anyone assist?
XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

txtText.setText("");

super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_SPEECH: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> text = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtText.setText(text.get(0));
}
break;
}
}
}
}

In your onActivityResult, you are overriding your TextView with the first word only(index 0).
You must iterate through the String array list like so:
String words = "";
for ( String word : text ) {
words += " " + word;
}
txtText.setText(words);
And here's a nice article to help you implement your ListView:
ListView tutorial
So now when you figured that out you add the words value in the listview.
Hope this helps,
Cheers
