好的，我已经设法解决了我所写的所有问题：
1.我改变了第三方库的工作方式（我不记得我从哪里得到库，但this one 非常相似），通过改变每一行的布局，以便标题位于内容本身的左侧。这只是一个布局 XML 文件的问题，您已经完成了很多工作。也许我会为这两种解决方案发布一个不错的库。
2.这是我的观点。这不是官方的实现（没有找到），所以我自己做了一些东西。它可以更高效，但至少它很容易理解并且相当灵活：
public class CircularView extends ViewSwitcher {
private ImageView mImageView;
private TextView mTextView;
private Bitmap mBitmap;
private CharSequence mText;
private int mBackgroundColor = 0;
private int mImageResId = 0;
public CircularView(final Context context) {
this(context, null);
}
public CircularView(final Context context, final AttributeSet attrs) {
super(context, attrs);
addView(mImageView = new ImageView(context), new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT, Gravity.CENTER));
addView(mTextView = new TextView(context), new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT, Gravity.CENTER));
mTextView.setGravity(Gravity.CENTER);
if (isInEditMode())
setTextAndBackgroundColor("", 0xFFff0000);
}
@Override
protected void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
final int measuredWidth = getMeasuredWidth();
final int measuredHeight = getMeasuredHeight();
if (measuredWidth != 0 && measuredHeight != 0)
drawContent(measuredWidth, measuredHeight);
}
@SuppressWarnings("deprecation")
private void drawContent(final int measuredWidth, final int measuredHeight) {
ShapeDrawable roundedBackgroundDrawable = null;
if (mBackgroundColor != 0) {
roundedBackgroundDrawable = new ShapeDrawable(new OvalShape());
roundedBackgroundDrawable.getPaint().setColor(mBackgroundColor);
roundedBackgroundDrawable.setIntrinsicHeight(measuredHeight);
roundedBackgroundDrawable.setIntrinsicWidth(measuredWidth);
roundedBackgroundDrawable.setBounds(new Rect(0, 0, measuredWidth, measuredHeight));
}
if (mImageResId != 0) {
mImageView.setBackgroundDrawable(roundedBackgroundDrawable);
mImageView.setImageResource(mImageResId);
mImageView.setScaleType(ScaleType.CENTER_INSIDE);
} else if (mText != null) {
mTextView.setText(mText);
mTextView.setBackgroundDrawable(roundedBackgroundDrawable);
// mTextView.setPadding(0, measuredHeight / 4, 0, measuredHeight / 4);
mTextView.setTextSize(measuredHeight / 5);
} else if (mBitmap != null) {
mImageView.setScaleType(ScaleType.FIT_CENTER);
mImageView.setBackgroundDrawable(roundedBackgroundDrawable);
mBitmap = ThumbnailUtils.extractThumbnail(mBitmap, measuredWidth, measuredHeight);
final RoundedBitmapDrawable roundedBitmapDrawable = RoundedBitmapDrawableFactory.create(getResources(),
mBitmap);
roundedBitmapDrawable.setCornerRadius((measuredHeight + measuredWidth) / 4);
mImageView.setImageDrawable(roundedBitmapDrawable);
}
resetValuesState(false);
}
public void setTextAndBackgroundColor(final CharSequence text, final int backgroundColor) {
resetValuesState(true);
while (getCurrentView() != mTextView)
showNext();
this.mBackgroundColor = backgroundColor;
mText = text;
final int height = getHeight(), width = getWidth();
if (height != 0 && width != 0)
drawContent(width, height);
}
public void setImageResource(final int imageResId, final int backgroundColor) {
resetValuesState(true);
while (getCurrentView() != mImageView)
showNext();
mImageResId = imageResId;
this.mBackgroundColor = backgroundColor;
final int height = getHeight(), width = getWidth();
if (height != 0 && width != 0)
drawContent(width, height);
}
public void setImageBitmap(final Bitmap bitmap) {
setImageBitmapAndBackgroundColor(bitmap, 0);
}
public void setImageBitmapAndBackgroundColor(final Bitmap bitmap, final int backgroundColor) {
resetValuesState(true);
while (getCurrentView() != mImageView)
showNext();
this.mBackgroundColor = backgroundColor;
mBitmap = bitmap;
final int height = getHeight(), width = getWidth();
if (height != 0 && width != 0)
drawContent(width, height);
}
private void resetValuesState(final boolean alsoResetViews) {
mBackgroundColor = mImageResId = 0;
mBitmap = null;
mText = null;
if (alsoResetViews) {
mTextView.setText(null);
mTextView.setBackgroundDrawable(null);
mImageView.setImageBitmap(null);
mImageView.setBackgroundDrawable(null);
}
}
public ImageView getImageView() {
return mImageView;
}
public TextView getTextView() {
return mTextView;
}
}
3.我找到了一个很好的库，叫做 PagerSlidingTabStrip 。不过，没有找到一种官方的方式来设置原生样式的样式。
另一种方法是查看 Google 的示例，该示例可直接在 Android-Studio 中使用，称为“SlidingTabLayout”。它显示了它是如何完成的。
编辑：#3 更好的库是here，也称为“PagerSlidingTabStrip”。
