Question

我按照android开发tutorial标签布局来实现简单的标签布局。

基于该教程，我脑子里有一个问题，那就是如何更改标签字体大小？

我尝试通过在布局 xml 文件的android:textSize="8dip"中添加属性<TabWidget ...>来更改标签字体大小：

<TabWidget
    android:id="@android:id/tabs"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"

    android:textSize="8dip" 
/>

但它没有任何效果。

任何人都可以提供更改标签上字体大小的正确方法吗？

Answer 1

您可以在此处使用

Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = (TabHost) getTabHost(); // The activity TabHost

TabHost.TabSpec spec; // Resusable TabSpec for each tab
Typeface localTypeface1 = Typeface.createFromAsset(getAssets(),
        "fonts/arial.ttf");

编辑开始

tabHost.getTabWidget().setBackgroundDrawable( getResources().getDrawable(R.drawable.bluenavbar));

修改结尾

TextView txtTab = new TextView(this);
txtTab.setText(getString(R.string.top_news));
txtTab.setPadding(8, 9, 8, 9);
txtTab.setTextColor(Color.WHITE);
txtTab.setTextSize(14);
txtTab.setTypeface(localTypeface1);
txtTab.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL);
txtTab.setBackgroundResource(R.drawable.tab_news);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("topNews").setIndicator(txtTab).setContent(new Intent(this, TopNewsGroup.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
tabHost.addTab(spec);

现在，您可以更改文字的颜色，尺寸和字体

Answer 2

如果你想实现它，你应该扩大标签的布局。

    tabHost = getTabHost(); // The activity TabHost
    tabHost.setOnTabChangedListener(this);
    Resources res = getResources(); // Resource object to get Drawables
    tabHost = getTabHost(); // The activity TabHost
    TabHost.TabSpec spec; // Reusable TabSpec for each tab

    TabSpec firstTabSpec = tabHost.newTabSpec("tid1");
    TabSpec secondTabSpec = tabHost.newTabSpec("tid2");
    TabSpec thirdTabSpec = tabHost.newTabSpec("tid3");
    TabSpec fourthTabSpec = tabHost.newTabSpec("tid4");
    TabSpec fifthTabSpec = tabHost.newTabSpec("tid5");

    viewCache[0] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);
    viewCache[1] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);
    viewCache[2] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);
    viewCache[3] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);
    viewCache[4] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);

    firstTabSpec.setIndicator(viewCache[0]);
    secondTabSpec.setIndicator(viewCache[1]);
    thirdTabSpec.setIndicator(viewCache[2]);
    fourthTabSpec.setIndicator(viewCache[3]);
    fifthTabSpec.setIndicator(viewCache[4]);

    firstTabSpec.setContent(new Intent(this, HomeTabActivityGroup.class));
    secondTabSpec
            .setContent(new Intent(this, ProfileTabActivityGroup.class));
    thirdTabSpec.setContent(new Intent(this,
            NotificationTabActivityGroup.class));
    fourthTabSpec.setContent(new Intent(this,
            FavoritesTabActivityGroup.class));
    fifthTabSpec
            .setContent(new Intent(this, MoreTabActivityGroupNew.class));

    tabHost.addTab(firstTabSpec);
    tabHost.addTab(secondTabSpec);
    tabHost.addTab(thirdTabSpec);
    tabHost.addTab(fourthTabSpec);
    tabHost.addTab(fifthTabSpec);

    currentTabvalue = tabHost.getCurrentTab();
    C2DMessaging.register(TennisAppActivity.mContext,
            "racquetester@gmail.com");
    for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {

        // tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#7392B5"));
        switch (i) {
        case 0:
            tabHost.getTabWidget().getChildAt(i)
                    .setBackgroundResource(R.drawable.home);
            break;
        case 1:
            tabHost.getTabWidget().getChildAt(i)
                    .setBackgroundResource(R.drawable.profile);
            break;
        case 2:
            tabHost.getTabWidget().getChildAt(i)
                    .setBackgroundResource(R.drawable.notifications);
            break;
        case 3:
            tabHost.getTabWidget().getChildAt(i)
                    .setBackgroundResource(R.drawable.fav);
            break;
        case 4:
            tabHost.getTabWidget().getChildAt(i)
                    .setBackgroundResource(R.drawable.more);
            break;
        }
    }

// <强> * ** * ** * ** * ** * ** * ** * ** * ** * ** * ** * ** * ** * *

这是tab1.xml

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout android:id="@+id/LinearLayout01" 
 android:layout_width="wrap_content" android:layout_height="wrap_content"
  xmlns:android="http://schemas.android.com/apk/res/android" android:gravity="center">
 <ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content"  android:layout_height="50dip"></ImageView>
   </LinearLayout>

您应该根据您的情况将testview放在图像视图和settest文本大小属性的位置。我希望这是有帮助的。

这是我的2美分，它对我有用......

首先在你的oncreate中添加

TabHost.TabSpec spec;  // Resusable TabSpec for each tab
    Intent intent;  // Reusable Intent for each tab
    MyView view = null;

然后在你的on创建中使用this for each tab ...

intent = new Intent().setClass(this, BrownieTab.class);
    view = new MyView(this, R.drawable.ic_tab_brownie_2, R.drawable.ic_tab_brownie_2, "Yourself");
    view.setBackgroundDrawable(this.getResources().getDrawable(R.layout.selecttabbackground));
    spec = tabHost.newTabSpec("inprogress").setIndicator(view).setContent(intent);
    tabHost.addTab(spec);

最后这是MyView ......

private class MyView extends LinearLayout {
    ImageView iv;
    TextView tv;

    public MyView(Context c, int drawable, int drawableselec, String label) {
        super(c);
        iv = new ImageView(c);
        StateListDrawable listDrawable = new StateListDrawable();
        listDrawable.addState(SELECTED_STATE_SET, this.getResources()
                .getDrawable(drawableselec));
        listDrawable.addState(ENABLED_STATE_SET, this.getResources()
                .getDrawable(drawable));
        iv.setImageDrawable(listDrawable);
        iv.setBackgroundColor(Color.TRANSPARENT);
        iv.setLayoutParams(new LayoutParams(48, 48, (float) 0.0));
        setGravity(Gravity.CENTER);
        tv = new TextView(c);
        tv.setText(label);
        tv.setGravity(Gravity.CENTER);
        tv.setBackgroundColor(Color.TRANSPARENT);
        tv.setTextColor(Color.BLACK);
        tv.setTextSize(12);

        tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT, (float) 1.0));
        setOrientation(LinearLayout.VERTICAL);
        addView(iv);
        addView(tv);
        setBackgroundDrawable(this.getResources().getDrawable(
                R.layout.selecttabbackground));
    }
}

您可以在我的视图中更改有关选项卡的所有属性，并在oncreate方法中更改文本和背景

Answer 4

我不是你可以改变TabWidget中的textSize 我只是检查您可以使用的属性，并且无法直接编辑您的文本。

唯一的方法是给自己的布局充气。
