android staticlayout的代码示例

在Android中，StaticLayout用于将文本内容布局化为一个矩形区域

import android.content.Context;
import android.graphics.Canvas;
import android.text.StaticLayout;
import android.text.TextPaint;
import android.text.TextUtils;

public class StaticLayoutExample {

    public static void main(String[] args) {
        Context context = new Context();
        String text = "Hello, this is a static layout example!";
        int width = 200;
        int height = 100;

        StaticLayout staticLayout = createStaticLayout(context, text, width, height);
        drawStaticLayout(staticLayout);
    }

    private static StaticLayout createStaticLayout(Context context, String text, int width, int height) {
        TextPaint textPaint = new TextPaint();
        textPaint.setTextSize(16);
        textPaint.setColor(0xFF000000);

        int numberOfLines = 3;
        StaticLayout staticLayout = new StaticLayout(text, 0, text.length(), textPaint, width, Layout.Alignment.ALIGN_NORMAL, numberOfLines, 0);

        return staticLayout;
    }

    private static void drawStaticLayout(StaticLayout staticLayout) {
        Canvas canvas = new Canvas();
        canvas.drawColor(0xFFFFFFFF); // Set background color
        staticLayout.draw(canvas);
    }
}

在这个示例中，我们首先创建了一个Context对象，然后定义了一个字符串text和布局的宽度和高度。接下来，我们使用createStaticLayout方法创建一个StaticLayout实例，传入文本、宽度、高度等参数。最后，我们使用drawStaticLayout方法将StaticLayout绘制到一个Canvas上。
