android staticlayout的代碼示例

在Android中，StaticLayout用于將文本內容布局化為一個矩形區域

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);
    }
}

在這個示例中，我們首先創建了一個Context對象，然后定義了一個字符串text和布局的寬度和高度。接下來，我們使用createStaticLayout方法創建一個StaticLayout實例，傳入文本、寬度、高度等參數。最后，我們使用drawStaticLayout方法將StaticLayout繪制到一個Canvas上。
