如何包装或对齐文字我使用相对布局我附上下面的图像

 <TextView
            android:id="@+id/txt_text_madina"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentRight="true"
            android:layout_below="@id/txt_desc_madina"
            android:layout_centerHorizontal="true"
            android:layout_gravity="center_vertical|left"
            android:layout_marginLeft="2dp"
            android:layout_marginTop="2dp"
            android:text="In front of the sacred tomb of The Holy Prophet (peace be upon him), there are three sections of brass screens and all three have holes in them. Look at the picture carefully. If you stand in front of the middle section between the pillars, you'll see a big round hole on your left. This is in front of the face of the Holy Prophet. Adjacent to it is a door that stays closed. Right after it on the right side is a round hole which is in front of the face of Hadrat Abu Bakr Siddique. On the right of it, there is another round hole which is in front of the face of Hadrat Umar Farooq."

Answer 1

Android不支持对齐，要在Android中使用WebView

来证明文本

 WebView view = new WebView(this);
    view.setVerticalScrollBarEnabled(false);

    ((LinearLayout)findViewById(R.id.inset_web_view)).addView(view);

    view.loadData(getString(R.string.hello), "text/html; charset=utf-8", "utf-8");

和html代码

<string name="hello">
<![CDATA[
<html>
 <head></head>
 <body style="text-align:justify;color:gray;background-color:black;">
  Lorem ipsum dolor sit amet, consectetur 
  adipiscing elit. Nunc pellentesque, urna
  nec hendrerit pellentesque, risus massa
 </body>
</html>
]]>
</string>

编辑：将背景设置为透明，请使用：

webView.setBackgroundColor(0x00000000); 
if (Build.VERSION.SDK_INT >= 11) webView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);

this.wv.setWebViewClient(new WebViewClient() { 

@Override public void onPageFinished(WebView view, String url) {                
      view.setBackgroundColor(0x00000000); if (Build.VERSION.SDK_INT >= 11) 
      view.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null); } });

创建一个新的Java类并添加以下代码

public class JustifiedTextView extends TextView {

    private int mLineY;
    private int mViewWidth;

    public JustifiedTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onLayout(boolean changed, int left, int top, int right,
            int bottom) {
        super.onLayout(changed, left, top, right, bottom);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        TextPaint paint = getPaint();
        paint.setColor(getCurrentTextColor());
        paint.drawableState = getDrawableState();
        mViewWidth = getMeasuredWidth();
        String text = (String) getText();
        mLineY = 0;
        mLineY += getTextSize();
        Layout layout = getLayout();
        for (int i = 0; i < layout.getLineCount(); i++) {
            int lineStart = layout.getLineStart(i);
            int lineEnd = layout.getLineEnd(i);
            String line = text.substring(lineStart, lineEnd);

            float width = StaticLayout.getDesiredWidth(text, lineStart,
                    lineEnd, getPaint());
            if (needScale(line)) {
                drawScaledText(canvas, lineStart, line, width);
            } else {
                canvas.drawText(line, 0, mLineY, paint);
            }

            mLineY += getLineHeight();
        }
    }

    private void drawScaledText(Canvas canvas, int lineStart, String line,
            float lineWidth) {
        float x = 0;
        if (isFirstLineOfParagraph(lineStart, line)) {
            String blanks = "  ";
            canvas.drawText(blanks, x, mLineY, getPaint());
            float bw = StaticLayout.getDesiredWidth(blanks, getPaint());
            x += bw;

            line = line.substring(3);
        }

        float d = (mViewWidth - lineWidth) / line.length() - 1;
        for (int i = 0; i < line.length(); i++) {
            String c = String.valueOf(line.charAt(i));
            float cw = StaticLayout.getDesiredWidth(c, getPaint());
            canvas.drawText(c, x, mLineY, getPaint());
            x += cw + d;
        }
    }

    private boolean isFirstLineOfParagraph(int lineStart, String line) {
        return line.length() > 3 && line.charAt(0) == ' '
                && line.charAt(1) == ' ';
    }

    private boolean needScale(String line) {
        if (line.length() == 0) {
            return false;
        } else {
            return line.charAt(line.length() - 1) != '\n';
        }
    }

}

转到xml布局文件并更改：

<TextView
            android:id="@+id/txt_text_madina"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentRight="true"
            android:layout_below="@id/txt_desc_madina"
            android:layout_centerHorizontal="true"
            android:layout_gravity="center_vertical|left"
            android:layout_marginLeft="2dp"
            android:layout_marginTop="2dp"
            android:text="In front of the sacred tomb of The Holy Prophet (peace be upon him), there are three sections of brass screens and all three have holes in them. Look at the picture carefully. If you stand in front of the middle section between the pillars, you'll see a big round hole on your left. This is in front of the face of the Holy Prophet. Adjacent to it is a door that stays closed. Right after it on the right side is a round hole which is in front of the face of Hadrat Abu Bakr Siddique. On the right of it, there is another round hole which is in front of the face of Hadrat Umar Farooq."
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@color/appscreen"

            />

带

<com.yourpackage.JustifiedTextView
            android:id="@+id/txt_text_madina"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentRight="true"
            android:layout_below="@id/txt_desc_madina"
            android:layout_centerHorizontal="true"
            android:layout_gravity="center_vertical|left"
            android:layout_marginLeft="2dp"
            android:layout_marginTop="2dp"
            android:text="In front of the sacred tomb of The Holy Prophet (peace be upon him), there are three sections of brass screens and all three have holes in them.

            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@color/appscreen"
            />
