直播系統app原始碼，TabLayout:自定義字型大小
直播系統app原始碼，TabLayout:自定義字型大小實現的相關程式碼
1、主程式碼
//方式一：
private String[] mTabs = new String[]{"案例", "宣傳"};
//方式二：動態生成資料
private String[] mTabs = {};
private List<String> firstList = new ArrayList<>();
firstList.add("案例");
firstList.add("宣傳");
mTabs = new String[firstList.size()];
firstList.toArray(mTabs);
private void initTab() {
addTab(tabLayout, position -> {
});
}
private void addTab(TabLayout tabLayout, OnTabChangedListener listener) {
for (String tab : mTabs) {
tabLayout.addTab(tabLayout.newTab().setText(tab));
}
tabLayout.setScrollableTabRadius(5);
tabLayout.setSelectedTabIndicatorWidth(70);
tabLayout.setIndicatorVerticalOffset(0);
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {//改變選中狀態下文字大小
@Override
public void onTabSelected(TabLayout.Tab tab) {
setCustomTab(tab, true);
if (listener != null) {
listener.onTabChanged(tab.getPosition());
}
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
setCustomTab(tab, false);
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
TabLayout.Tab tab = tabLayout.getTabAt(0);
if (tab != null) {
setCustomTab(tab, true);
}
}
private void setCustomTab(TabLayout.Tab tab, boolean isSelected) {
tab.setCustomView(null);
int color = Color.parseColor("#999999");
int size = 15;
if (isSelected) {
color = Color.parseColor("#333333");
size = 18;
}
@SuppressLint("InflateParams") TextView textView = (TextView) LayoutInflater.from(context).inflate(R.layout.item_tab_text, null);
textView.setTextSize(size);
textView.setTextColor(color);
textView.setText(tab.getText());
tab.setCustomView(textView);
}
2、自定義介面
public interface OnTabChangedListener {
void onTabChanged(int position);
}
3、xml
<com.x.common.widget.tablayout.TabLayout android:id="@+id/tl_title" android:layout_width="match_parent" android:layout_height="50dp" android:background="#ffffff" android:paddingTop="10dp" android:paddingBottom="6dp" app:tabGravity="center" app:tabIndicatorColor="@color/colorPrimary" app:tabIndicatorHeight="4dp" app:tabPaddingBottom="4dp" app:tabSelectedTextColor="@color/colorPrimary" /> <com.x.common.widget.MyTextView xmlns:android=" xmlns:app=" android:textSize="16sp" android:layout_gravity="center" android:gravity="center" android:textColor="@color/color_333" android:layout_width="wrap_content" app:tv_bottom_height="15dp" app:tv_bottom_width="20dp" android:layout_height="wrap_content"> </com.zswl.common.widget.MyTextView>
4、MyTextView
@SuppressLint("AppCompatCustomView")
public class MyTextView extends AppCompatTextView {
private float mLeftWidth;
private float mLeftHeight;
private float mTopWidth;
private float mTopHeight;
private float mRightWidth;
private float mRightHeight;
private float mBottomWidth;
private float mBottomHeight;
public MyTextView(Context context) {
super(context);
}
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
TypedArray t = context.obtainStyledAttributes(attrs, R.styleable.MyTextView);
mLeftWidth = t.getDimension(R.styleable.MyTextView_tv_left_width, dip2px(context, 15));
mLeftHeight = t.getDimension(R.styleable.MyTextView_tv_left_height, dip2px(context, 15));
mTopWidth = t.getDimension(R.styleable.MyTextView_tv_top_width, dip2px(context, 15));
mTopHeight = t.getDimension(R.styleable.MyTextView_tv_top_height, dip2px(context, 15));
mRightWidth = t.getDimension(R.styleable.MyTextView_tv_right_width, dip2px(context, 15));
mRightHeight = t.getDimension(R.styleable.MyTextView_tv_right_height, dip2px(context, 15));
mBottomWidth = t.getDimension(R.styleable.MyTextView_tv_bottom_width, dip2px(context, 15));
mBottomHeight = t.getDimension(R.styleable.MyTextView_tv_bottom_height, dip2px(context, 15));
t.recycle();
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
//讓RadioButton的圖示可調大小 屬性：
Drawable drawableLeft = this.getCompoundDrawables()[0];//獲得文字左側圖片
Drawable drawableTop = this.getCompoundDrawables()[1];//獲得文字頂部圖片
Drawable drawableRight = this.getCompoundDrawables()[2];//獲得文字右側圖片
Drawable drawableBottom = this.getCompoundDrawables()[3];//獲得文字底部圖片
if (drawableLeft != null) {
drawableLeft.setBounds(0, 0, (int) mLeftWidth, (int) mLeftHeight);
}
if (drawableTop != null) {
drawableTop.setBounds(0, 0, (int) mTopWidth, (int) mTopHeight);
}
if (drawableRight != null) {
drawableRight.setBounds(0, 0, (int) mRightWidth, (int) mRightHeight);
}
if (drawableBottom != null) {
drawableBottom.setBounds(0, 0, (int) mBottomWidth, (int) mBottomHeight);
}
this.setCompoundDrawables(drawableLeft, drawableTop, drawableRight, drawableBottom);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
public static int dip2px(Context context, float dpValue) {
float scale = context.getResources().getDisplayMetrics().density;
return (int) (dpValue * scale + 0.5f);
}
public void setDrawableRight(@DrawableRes int drawableRight) {
Drawable drawableEnd = getResources().getDrawable(drawableRight);
int size = dip2px(getContext(), 10);
drawableEnd.setBounds(0, 0, size, size);
setCompoundDrawables(null, null, drawableEnd, null);
setCompoundDrawablePadding(size);
}
public void setDrawableRight(@DrawableRes int drawableRight, int size, int padding) {
Drawable drawableEnd = getResources().getDrawable(drawableRight);
size = dip2px(getContext(), size);
drawableEnd.setBounds(0, 0, size, size);
setCompoundDrawables(null, null, drawableEnd, null);
setCompoundDrawablePadding(dip2px(getContext(), padding));
}
public void setDrawableLeft(@DrawableRes int drawableRight, int size, int padding) {
Drawable drawableStart = getResources().getDrawable(drawableRight);
size = dip2px(getContext(), size);
drawableStart.setBounds(0, 0, size, size);
setCompoundDrawables(drawableStart, null, null, null);
setCompoundDrawablePadding(dip2px(getContext(), padding));
}
public void setDrawableTop(@DrawableRes int top, int size, int padding) {
Drawable drawableTop = getResources().getDrawable(top);
size = dip2px(getContext(), size);
drawableTop.setBounds(0, 0, size, size);
setCompoundDrawables(null, drawableTop, null, null);
setCompoundDrawablePadding(dip2px(getContext(), padding));
}
public void setDrawableTop(@DrawableRes int drawableTop) {
Drawable drawabletop = getResources().getDrawable(drawableTop);
int size = dip2px(getContext(), 10);
drawabletop.setBounds(0, 0, size, size);
setCompoundDrawables(null, drawabletop, null, null);
setCompoundDrawablePadding(size);
}
public void setDrawableBottom(@DrawableRes int bottom, int size, int padding) {
Drawable drawableBottom = getResources().getDrawable(bottom);
size = dip2px(getContext(), size);
drawableBottom.setBounds(0, 0, size, size);
setCompoundDrawables(null, null, null, drawableBottom);
setCompoundDrawablePadding(dip2px(getContext(), padding));
}
public void setDrawableLeft(@DrawableRes int drawableLeft) {
Drawable drawableStart = getResources().getDrawable(drawableLeft);
int size = dip2px(getContext(), 15);
drawableStart.setBounds(0, 0, size, size);
setCompoundDrawables(drawableStart, null, null, null);
setCompoundDrawablePadding(dip2px(getContext(), 5));
}
public void setDrawableNone() {
setCompoundDrawables(null, null, null, null);
}
}
5、自定義屬性
<declare-styleable name="MyTextView"> <attr name="tv_left_width" format="dimension" /> <attr name="tv_left_height" format="dimension" /> <attr name="tv_top_width" format="dimension" /> <attr name="tv_top_height" format="dimension" /> <attr name="tv_right_width" format="dimension" /> <attr name="tv_right_height" format="dimension" /> <attr name="tv_bottom_width" format="dimension" /> <attr name="tv_bottom_height" format="dimension" /> </declare-styleable>
