android – 更改Justified TextView的字体

2019年7月20日 194次阅读

我想在TextView中使用合理的文本格式,所以我创建了类JustifiedTextView扩展WebView.

但我无法设置外部字体.

我在我的代码中尝试了setTypeface,它没有给出任何错误,但TextView中没有设置Typeface.

我班级中与字体有关的任何变化？

.XML

<com.example.Model.JustifiedTextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:id="@id/article_decription" />

JustifiedTextView.Java

public class JustifiedTextView extends WebView {

    private String core = "<html><body style='text-align:justify;color:rgba(%s);font-size:%dpx;margin: 10px 10px 10px 10px;'>%s</body></html>";
    private String textColor = "0,0,0,255";
    private String text = "";

    String fontBody = "fonts/AvenirLTStd-Book.otf";

    Typeface typeFace = Typeface.createFromAsset(getContext().getAssets(), fontBody);
    private int textSize = 18;
    private int backgroundColor = Color.TRANSPARENT;
    public JustifiedTextView(Context context, AttributeSet attrs){
        super(context, attrs);
        this.setWebChromeClient(new WebChromeClient() {
        });
    }

    public void setText(String s) {
        this.text = s;
        // this.setPadding(10, 10, 10, 10);
        reloadData();
    }

    @SuppressLint("NewApi")
    private void reloadData() {
        // loadData(...) has a bug showing utf-8 correctly. That's why we need
        // to set it first.
        // this.getSettings().setDefaultTextEncodingName("utf-8");

        this.loadData(String.format(core, textColor, textSize, text, typeFace), "text/html", "utf-8");
        // set WebView's background color *after* data was loaded.
        super.setBackgroundColor(backgroundColor);
        // Hardware rendering breaks background color to work as expected.
        // Need to use software renderer in that case.
        if (android.os.Build.VERSION.SDK_INT >= 11)
            this.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);
    }

    public void setTextColor(int hex) {
        String h = Integer.toHexString(hex);
        int a = Integer.parseInt(h.substring(0, 2), 16);
        int r = Integer.parseInt(h.substring(2, 4), 16);
        int g = Integer.parseInt(h.substring(4, 6), 16);
        int b = Integer.parseInt(h.substring(6, 8), 16);
        textColor = String.format("%d,%d,%d,%d", r, g, b, a);
        reloadData();
    }

    public void setBackgroundColor(int hex) {
        backgroundColor = hex;
        reloadData();
    }

    public void setTextSize(int textSize) {
        this.textSize = textSize;
        reloadData();
    }

    public void setTypeFace(Typeface typeFace){
        this.typeFace=typeFace;
        reloadData();
    }
}

MainActivity.Java

Typeface typeFontBody = Typeface.createFromAsset(getAssets(), fontBody);
JustifiedTextView Description;
Description = (JustifiedTextView)itemView.findViewById(R.id.article_decription);
Description.setTypeFace(typeFontBody);
Description.setText("Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book");
