android set text to arraylist of textviews

Question

How to set text to an array of TextViews.

This is what I made:

public void onClickButtons(View view) { if(view==mBtnGuess) { int i; String word = "someword"; String getInput = mEtxtUserInput.getText().toString(); char[] wordChars = word.toCharArray(); if(getInput.length()>0) { if(getInput.length()==1) { List<TextView> txtCharArr= new ArrayList<TextView>(); txtCharArr.add(mChar1); txtCharArr.add(mChar2); txtCharArr.add(mChar3); txtCharArr.add(mChar4); txtCharArr.add(mChar5); txtCharArr.add(mChar6); txtCharArr.add(mChar7); txtCharArr.add(mChar8); txtCharArr.add(mChar9); txtCharArr.add(mChar10); txtCharArr.add(mChar11); txtCharArr.add(mChar12); StringBuilder sb = new StringBuilder(); for(i=0;i<wordChars.length;i++) { if(wordChars[i]==(word.charAt(i))) { txtCharArr.get(i).setText(word.charAt(i)); sb.append(word.charAt(i)); } } } } } }

The stringbuilder is just to save all chars that where equal. the above code gives an error:

03-14 07:44:27.387: E/AndroidRuntime(1893): FATAL EXCEPTION: main 03-14 07:44:27.387: E/AndroidRuntime(1893): java.lang.IllegalStateException: Could not execute method of the activity 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.view.View$1.onClick(View.java:3591) 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.view.View.performClick(View.java:4084) 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.view.View$PerformClick.run(View.java:16966) 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.os.Handler.handleCallback(Handler.java:615) 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.os.Handler.dispatchMessage(Handler.java:92) 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.os.Looper.loop(Looper.java:137) 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.app.ActivityThread.main(ActivityThread.java:4745) 03-14 07:44:27.387: E/AndroidRuntime(1893): at java.lang.reflect.Method.invokeNative(Native Method) 03-14 07:44:27.387: E/AndroidRuntime(1893): at java.lang.reflect.Method.invoke(Method.java:511) 03-14 07:44:27.387: E/AndroidRuntime(1893): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 03-14 07:44:27.387: E/AndroidRuntime(1893): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 03-14 07:44:27.387: E/AndroidRuntime(1893): at dalvik.system.NativeStart.main(Native Method) 03-14 07:44:27.387: E/AndroidRuntime(1893): Caused by: java.lang.reflect.InvocationTargetException 03-14 07:44:27.387: E/AndroidRuntime(1893): at java.lang.reflect.Method.invokeNative(Native Method) 03-14 07:44:27.387: E/AndroidRuntime(1893): at java.lang.reflect.Method.invoke(Method.java:511) 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.view.View$1.onClick(View.java:3586) 03-14 07:44:27.387: E/AndroidRuntime(1893): ... 11 more 03-14 07:44:27.387: E/AndroidRuntime(1893): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x76 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.content.res.Resources.getText(Resources.java:229) 03-14 07:44:27.387: E/AndroidRuntime(1893): at android.widget.TextView.setText(TextView.java:3620) 03-14 07:44:27.387: E/AndroidRuntime(1893): at me.mikey.my.games.galgjex.Galgje.onClickButtons(Galgje.java:232)

line 232 is:

txtCharArr.get(i).setText(word.charAt(i));

I also tried:

public void onClickButtons(View view) { if(view==mBtnGuess) { int i; String word = "someword"; String getInput = mEtxtUserInput.getText().toString(); if(getInput.length()>0) { if(getInput.length()==1) { List<TextView> txtCharArr= new ArrayList<TextView>(); txtCharArr.add(mChar1); txtCharArr.add(mChar2); txtCharArr.add(mChar3); txtCharArr.add(mChar4); txtCharArr.add(mChar5); txtCharArr.add(mChar6); txtCharArr.add(mChar7); txtCharArr.add(mChar8); txtCharArr.add(mChar9); txtCharArr.add(mChar10); txtCharArr.add(mChar11); txtCharArr.add(mChar12); StringBuilder sb = new StringBuilder(); for(i=0;i<getInput.length();i++) { if(getInput.equals(word.charAt(i))) { txtCharArr.get(i).setText(word.charAt(i)); sb.append(word.charAt(i)); } } } } } }

But this doesn't show anything. the StringBuilder is empty and there are no characters shown in the textViews when I input a character that should match.

can you give clarity on your question?

Because there is no TextView.setText(char x), your char is cast to an int, and TextView.setText(int x) is called, which searches for the resource with id x.

You should pass a String to the setText() method. You can try

txtCharArr.get(i).setText(Character.toString(word.charAt(i)));

or

txtCharArr.get(i).setText(word.subString(i, i+1)));

I changed it but it still doest show me anything. StringBuilder sb = new StringBuilder(); for(i=0;i<getInput.length();i++) { if(getInput.equals(word.charAt(i))) { txtCharArr.get(i).setText(Character.toString(word.charAt(i))); sb.append(Character.toString(word.charAt(i))); } }

You were asking two questions in stead of one. This solves your first question... You could edit your question(s), so only the first part remains, and next ask a new question for your second problem...
