【问题描述】:
如何设置平板电脑的标签图标大小我做了很多研究,尝试了很多方法,但无法使其适应我的布局。手机屏幕正常,但平板电脑屏幕上的“7”“10”图标尺寸仍然很小。
public class MainActivity extends AppCompatActivity {
private TabLayout tabLayout;
private ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
setupTabIcons();
我以编程方式获取图标。
}
private void setupTabIcons() {
TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabOne.setText(R.string.Scanner);
tabOne.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_image, 0, 0);
tabLayout.getTabAt(0).setCustomView(tabOne);
TextView tabTwo = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabTwo.setText(R.string.Create);
tabTwo.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.create, 0, 0);
tabLayout.getTabAt(1).setCustomView(tabTwo);
TextView tabThree = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabThree.setText(R.string.History);
tabThree.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_history, 0, 0);
tabLayout.getTabAt(2).setCustomView(tabThree);
TextView tabFour = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabFour.setText(R.string.Settings);
tabFour.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_settings, 0, 0);
tabLayout.getTabAt(3).setCustomView(tabFour);
}
}
我的 activity_main 布局
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<com.google.android.material.tabs.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="@dimen/_45sdp"
app:tabGravity="fill"
app:tabMode="fixed" />
</com.google.android.material.appbar.AppBarLayout>
custom_tab 布局
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif"
android:gravity="center_horizontal"
android:textColor="@color/custom_tabtext1"
android:textSize="@dimen/_9ssp"
/>
