Question

我想要2个textviews来保持这样的

textview1 textview1 textview1 textview1 textview1 textview1 textview1 textview1 textview1 textview1 textview1 textview1 textview1 textview1|textView2 textView2 textView2 textView2

textview1的长度可能超过1行，textview2必须在textview1与textview1结束的同一行之后保持正确。有什么想法吗？

你可以使用课程

public class PredicateLayout extends ViewGroup {

public static final int DEFAULT_HORIZONTAL_SPACING = 0;
public static final int DEFAULT_VERTICAL_SPACING = 0;
private final int horizontalSpacing;
private final int verticalSpacing;
private List<RowMeasurement> currentRows = Collections.emptyList();

public PredicateLayout(Context context, AttributeSet attrs) {
    super(context, attrs);
    TypedArray styledAttributes = context.obtainStyledAttributes(attrs, R.styleable.RowLayout);
    horizontalSpacing = styledAttributes.getDimensionPixelSize(R.styleable.RowLayout_android_horizontalSpacing,
            DEFAULT_HORIZONTAL_SPACING);
    verticalSpacing = styledAttributes.getDimensionPixelSize(R.styleable.RowLayout_android_verticalSpacing,
            DEFAULT_VERTICAL_SPACING);
    styledAttributes.recycle();
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    final int widthMode = MeasureSpec.getMode(widthMeasureSpec);
    final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
    final int maxInternalWidth = MeasureSpec.getSize(widthMeasureSpec) - getHorizontalPadding();

        int childHeightSpec = createChildMeasureSpec(childLayoutParams.height, maxInternalHeight, heightMode);
        child.measure(childWidthSpec, childHeightSpec);
        int childWidth = child.getMeasuredWidth();
        int childHeight = child.getMeasuredHeight();
        if (currentRow.wouldExceedMax(childWidth)) {
            currentRow = new RowMeasurement(maxInternalWidth, widthMode);
            rows.add(currentRow);
        }
        currentRow.addChildDimensions(childWidth, childHeight);
    }

    int longestRowWidth = 0;

        RowMeasurement row = rows.get(index);

        child.layout(x, y, x + childWidth, y + childHeight);

    }
}

private List<View> getLayoutChildren() {
    List<View> children = new ArrayList<View>();
    for (int index = 0; index < getChildCount(); index++) {
        View child = getChildAt(index);
        if (child.getVisibility() != View.GONE) {
            children.add(child);
        }
    }
    return children;
}

protected int getVerticalPadding() {
    return getPaddingTop() + getPaddingBottom();
}

protected int getHorizontalPadding() {
    return getPaddingLeft() + getPaddingRight();
}

private final class RowMeasurement {
    private final int maxWidth;
    private final int widthMode;
    private int width;
    private int height;

    public RowMeasurement(int maxWidth, int widthMode) {
        this.maxWidth = maxWidth;
        this.widthMode = widthMode;
    }

    public int getHeight() {
        return height;
    }

    public int getWidth() {
        return width;
    }

    public boolean wouldExceedMax(int childWidth) {
        return widthMode == MeasureSpec.UNSPECIFIED ? false : getNewWidth(childWidth) > maxWidth;
    }

    public void addChildDimensions(int childWidth, int childHeight) {
        width = getNewWidth(childWidth);
        height = Math.max(height, childHeight);
    }

    private int getNewWidth(int childWidth) {
        return width == 0 ? childWidth : width + horizontalSpacing + childWidth;
    }
}

}

的xml：

<com.yourpackage.PredicateLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

       <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="TextView1" />
       <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="TextView1" />
       <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="TextView2" />

    </com.yourpackage.PredicateLayout>

修改你需要在/res/values/attrs.xml下创建xml

<?xml version="1.0" encoding="utf-8"?> <resources> <declare-styleable name="RowLayout"> <attr name="android:verticalSpacing" /> <attr name="android:horizontalSpacing" /> </declare-styleable> </resources>

我知道的三种方式，可能存在更好的方式：

1）在Html中加载文本并将其设置为文本视图（您可以使用html样式和...）

String text = "<font color=#cc0029>"+text1+"</font> <font color=#ffcc00>"+text2+"</font>";
textView.setText(Html.fromHtml(text));

2）在一个文本视图中加载文本，但为文本的每个部分设置spannable 3）创建自定义TextView类并计算文本长度然后如果大于您想要在此下面设置另一个textview布局

Answer 3

我写了一个新的TextViewUtil来处理这种情况并将其发布在这里以防其他人正在寻找这种麻烦：

public class TextViewUtil {

public static void setClickableText(Context context, TextView view, String clickableText, OnClickListener listener) {

    CharSequence text = view.getText();
    String string = text.toString();
    Resources resources = context.getResources();
    ClickSpan span = new ClickSpan(listener, resources.getColor(R.color.background_blue),
            resources.getColor(R.color.universal_profile_blue_link));

    int start = string.indexOf(clickableText);
    int end = start + clickableText.length();
    if (start == -1)
        return;

    if (text instanceof Spannable) {
        ((Spannable) text).setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        view.setText(text);
    } else {
        SpannableString s = SpannableString.valueOf(text);
        s.setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        view.setText(s);
    }

    MovementMethod m = view.getMovementMethod();
    if (m == null || !(m instanceof LinkTouchMovementMethod)) {
        view.setMovementMethod(LinkTouchMovementMethod.getInstance());
    }
}
}
