使用共享的首选项更改字体样式

Question

Code

Button mButton1;
String mDefaultFont1;
SharedPreferences mSharedPreferences1;
SharedPreferences.Editor editor1;

 mButton1 = (Button)findViewById(R.id.buttontextfontsent);
 mSharedPreferences1 = PreferenceManager.getDefaultSharedPreferences(this);
 mDefaultFont1 = mSharedPreferences1.getString("Default_Font1","Normal");
 mButton1.setTypeface(mButton1.getTypeface(),Typeface.NORMAL);

mButton1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        final String[] list = new String[]{"Normal", "Bold", "Italic", "Bold ITalic"};
        AlertDialog.Builder builder = new AlertDialog.Builder(CustomizeFont.this);
        builder.setTitle("Make your selection");
        builder.setItems(list, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int item) {
                if (item==0) mButton1.setTypeface(mButton1.getTypeface(),Typeface.NORMAL);
                if (item==1) mButton1.setTypeface(mButton1.getTypeface(),Typeface.BOLD);
                if (item==2) mButton1.setTypeface(mButton1.getTypeface(),Typeface.ITALIC);
                if (item==3) mButton1.setTypeface(mButton1.getTypeface(),Typeface.BOLD_ITALIC);
                editor1 = PreferenceManager.getDefaultSharedPreferences(CustomizeFont.this).edit();
                 editor1.putString("Default_Font1", String.valueOf(item));
                editor1.apply();

            }
        });
        builder.show();
    }
});

I can change the font but when i restart the activity it goes back to the original normal font... the problem is because of this line mButton1.setTypeface(mButton1.getTypeface(),Typeface.NORMAL);

I need to set the TypeFace.NORMAL to Default_Font1 But not accepting... what should I do?

I need to set the textview to Default_Font1 But not accepting... what should I do?

You need to setTypeface in your button based on you values getting from SharedPreferences

SAMPLE CODE

mDefaultFont1 = mSharedPreferences1.getString("Default_Font1","0");
if (mDefaultFont1.equals("0")) {
    mButton1.setTypeface(mButton1.getTypeface(), Typeface.NORMAL);
} else if (mDefaultFont1.equals("1")) {
    mButton1.setTypeface(mButton1.getTypeface(), Typeface.BOLD);
} else if (mDefaultFont1.equals("2")) {
    mButton1.setTypeface(mButton1.getTypeface(), Typeface.ITALIC);
} else if (mDefaultFont1.equals("3")) {
    mButton1.setTypeface(mButton1.getTypeface(), Typeface.BOLD_ITALIC);
}

mButton1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

    final String[] list = new String[]{"Normal", "Bold", "Italic", "Bold ITalic"};
    AlertDialog.Builder builder = new AlertDialog.Builder(CustomizeFont.this);
    builder.setTitle("Make your selection");
    builder.setItems(list, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) {
            if (item==0) mButton1.setTypeface(null);
            if (item==1) mButton1.setTypeface(mButton1.getTypeface(),Typeface.BOLD);
            if (item==2) mButton1.setTypeface(mButton1.getTypeface(),Typeface.ITALIC);
            if (item==3) mButton1.setTypeface(mButton1.getTypeface(),Typeface.BOLD_ITALIC);
            editor1 = PreferenceManager.getDefaultSharedPreferences(CustomizeFont.this).edit();
             editor1.putString("Default_Font1", String.valueOf(item));
            editor1.apply();

        }
    });
    builder.show();
 }
 });

Answer 2

try this .

editor.putInt("fontCode",mButton1.getTypeFace().getStyle());

and then use it as normal shared prefrence

Answer 3

mDefaultFont1 = mSharedPreferences1.getString("Default_Font1","Normal");
mButton1.setTypeface(mButton1.getTypeface(),Typeface.NORMAL);

This logic is completely wrong, keep in mind that you're saving int values in preferences (0, 1, 2, 3), but first you load it as if it was string with default value "normal".

In the second line you're setting the typeface for the button, but taking current typeface from same button, so what you get? No change.

Instead of that, I suggest something like this:

mDefaultFont1 = mSharedPreferences1.getInt("Default_Font1",0);
mButton1.setTypeface(mDefaultFont1);

And save the preference like this:

public void onClick(DialogInterface dialog, int item) {
    int defaultTypeface = 0;
    if (item==0) defaultTypeface = Typeface.NORMAL;
    if (item==1) defaultTypeface = Typeface.BOLD;
    if (item==2) defaultTypeface = Typeface.ITALIC;
    if (item==3) defaultTypeface = Typeface.BOLD_ITALIC;
    mButton1.setTypeface(defaultTypeface);
    editor1 = PreferenceManager.getDefaultSharedPreferences(CustomizeFont.this).edit();
    editor1.putInt("Default_Font1", defaultTypeface);
    editor1.apply();

}

Note, my code might be bit wrong, since I did write it from memory and didn't check if it's really fine.
