Question

我得到了这个，

"title": "=?UTF-8?Q?=E2=80=9CUber=E2=80=99s_Complicit_Board=E2=80=9D_published_?= =?UTF-8?Q?in_Monday_Note_by_Jean-Louis_Gass=C3=A9e?=",  //here

我收到了以下josn数据，

您需要解码标题字符串，因此请检查以下代码。

import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Matrix;
import android.graphics.Paint;
import android.graphics.Rect;
import android.graphics.RectF;
import android.graphics.Shader;
import android.graphics.drawable.GradientDrawable;

public class VoiceDrawable extends GradientDrawable {
    private static final float DEFAULT_LEVEL = 0.5f;

    private Paint levelPaint;
    private Paint viewPaint;
    private BitmapShader bitmapShader;
    private Matrix shaderMatrix;
    private float radius;

    private float level;

    public VoiceDrawable() {
        super();
        init();
    }

    private void init() {
        levelPaint = new Paint();
        levelPaint.setStyle(Paint.Style.FILL);

        viewPaint = new Paint();
        shaderMatrix = new Matrix();
    }

    public void setCornerRadius(float radius) {
        super.setCornerRadius(radius);

        this.radius = radius;
    }

    public void setVoice(float level) {
        this.level = level;

        invalidateSelf();
    }

    public void setLevelColor(int color) {
        levelPaint.setColor(color);
    }

    @Override
    public void draw(Canvas canvas) {
        super.draw(canvas);

        Rect rect = getBounds();
        if (bitmapShader == null) {
            initLevel(rect);
        }
        float scale = level == 0 ? 100 : (1 - level) / (1 - DEFAULT_LEVEL);
        shaderMatrix.setScale(1, scale, 0, DEFAULT_LEVEL);
        bitmapShader.setLocalMatrix(shaderMatrix);

        float rad = Math.min(radius, Math.min(rect.width(), rect.height()) * 0.5f);
        canvas.drawRoundRect(new RectF(rect), rad, rad, viewPaint);
    }

    private void initLevel(Rect rect) {
        Bitmap bitmap = Bitmap.createBitmap(rect.width(), rect.height(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        canvas.drawRect(rect.left, rect.top + rect.height() * (1 - DEFAULT_LEVEL), rect.right, rect.bottom, levelPaint);

        bitmapShader = new BitmapShader(bitmap, Shader.TileMode.REPEAT, Shader.TileMode.CLAMP);
        viewPaint.setShader(bitmapShader);
    }
}

这是来自RFC 2047的“编码字”编码。

这里有一个在线解码器：http://dogmamix.com/MimeHeadersDecoder/

libetpan可以解码它（参见mailmime_encoded_word_parse 在https://github.com/dinhviethoa/libetpan/blob/master/src/low-level/mime/mailmime_decode.c）。如果你只关心这个领域，这是非常重量级的。你可以自己编写一个基于RFC的解码器。

我以UTF 8格式获取标题的json数据，然后如何解决它？
