android develop log 2 - custom control xml and code

1.android control set style by code

answer:

I do not believe you can set the style programatically. To get around this you can create a template layout xml file with the style assigned, for example in res/layout create tvtemplate.xml as with the following content:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="This is a template"
        style="@style/my_style" />

then inflate this to instantiate your new TextView:

TextView myText = (TextView)getLayoutInflater().inflate(R.layout.tvtemplate, null);

Hope this helps.

2.android remote icon from tabhost control

answer:

create one tab class:

public class NoIconTab extends LinearLayout {
    public NoIconTab(Context c, int drawable, String label) {
        super(c);

        TextView tv = new TextView(c);
        
        tv.setTextColor(getResources().getColorStateList(R.color.tab_text_color));
        tv.setTextSize(TypedValue.COMPLEX_UNIT_SP, 10);
        tv.setGravity(0x01);

        setOrientation(LinearLayout.VERTICAL);

        if (drawable != 0) {
            ImageView iv = new ImageView(c);
            iv.setImageResource(drawable);
            addView(iv);
        }
        addView(tv);
    }
}

then used it by code:

mTabHost.addTab(mTabHost.newTabSpec("call_log")
                    .setIndicator(new NoIconTab(this,0,this.getResources().getString(R.string.scene)))
                    .setContent(intent));
