Question

我创建了一个自定义视图，允许我对文本进行描边。到目前为止它工作得非常好，我目前唯一的问题是它没有包含内容。它实际上似乎填满了整个父母。

我只需要它来包装文本，这样我就可以将其余的设计恢复到创建自定义视图之前的状态。

这是我的班级

public class DrawText extends View {

    String text = "blank";
    float textSize = 90;
    Context context;

    public DrawText(Context context, AttributeSet attrs)
    {
        super(context, attrs);

        this.context = context;
        TypedArray a = context.getTheme().obtainStyledAttributes(attrs, R.styleable.DrawText, 0, 0);

        try{
            text = a.getString(R.styleable.DrawText_titleText);
        }
        finally
        {
            a.recycle();
        }
    }

    public void setTextSize(float size) {this.textSize = size;}

    public void setText(String text) {this.text = text;}

    public String getText() {return text;}

    @Override
    public void draw(Canvas canvas)
    {
        Typeface font = Typeface.create(Typeface.DEFAULT, Typeface.ITALIC);
        TextPaint strokePaint = new TextPaint();
        strokePaint.setColor(Color.BLACK);
        strokePaint.setTextAlign(Paint.Align.CENTER);
        strokePaint.setTextSize(90);
        strokePaint.setStyle(Paint.Style.STROKE);
        strokePaint.setStrokeWidth(4);
        strokePaint.setDither(true);
        strokePaint.setStrokeJoin(Paint.Join.ROUND);
        strokePaint.setStrokeCap(Paint.Cap.ROUND);
        strokePaint.setAntiAlias(true);

        strokePaint.setTypeface(font);

        TextPaint textPaint = new TextPaint();
        textPaint.setColor(Color.WHITE);
        textPaint.setTextAlign(Paint.Align.CENTER);
        textPaint.setTextSize(90);
        textPaint.setTypeface(font);
        textPaint.setDither(true);
        textPaint.setAntiAlias(true);
        textPaint.setShadowLayer(1, 4, 4, Color.BLACK);

        StaticLayout mTextLayout = new StaticLayout(text, textPaint, canvas.getWidth(), Layout.Alignment.ALIGN_NORMAL, 1.0f, 1.0f, false);
        StaticLayout mStrokeLayout = new StaticLayout(text, strokePaint, canvas.getWidth(), Layout.Alignment.ALIGN_NORMAL, 1.0f, 1.0f, false);

        int textHeight = (getHeight()/2) - (mTextLayout.getHeight()/2);
        int textWidth = (getWidth()/2);

        canvas.translate(textWidth, textHeight);

        mStrokeLayout.draw(canvas);
        mTextLayout.draw(canvas);

        super.draw(canvas);
    }
}

在我的布局中使用如下。

<com.example.sw_stage.fancomglass.Drawables.DrawText
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:titleText="@string/streaming_fromcontacts"
            android:layout_toRightOf="@+id/contact_image"
            android:id="@+id/contact_name" />

我是新手使用自定义视图，我认为我应该使用onMeasure方法做一些事情，但我无法如何使用它来实现我的目标。

父视图填充父视图，而它应该只包含内容
