Android水平居中放置TextView，同时保持左对齐 [英] Android center TextView horizontally while keeping left align

问题描述

正如我的标题所述，我希望TextView中的文本在其父元素中水平居中，同时保持文本对齐：

As my title describes, I want the text in a TextView to be horizontally centered in it's parent element while keeping the text left aligned:

所以这： p>

So this:

|     Text     |
|   TextText   |

变为：

|   Text       |
|   TextText   |

Android可能吗？

Is this possible with Android?

这是我当前的布局：

<TextView
  android:layout_width="0dp"
  android:layout_height="match_parent"
  android:layout_weight="0.25"
  android:background="@drawable/table_cell"
  android:gravity="center"
  android:text="@string/table_last_training" />

在此先感谢

推荐答案

private String hackSpace(Context context, float textSize, String text) {
    TextView textView = new TextView(context);
    textView.setTextSize(textSize);
    ViewGroup.LayoutParams textViewParams = new ViewGroup.LayoutParams(WRAP_CONTENT, WRAP_CONTENT);
    textView.setLayoutParams(textViewParams);
    String[] sentences = text.split("\n");
    //calculate space width
    textView.setText(" ");
    textView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
    int slice = textView.getMeasuredWidth();
    //calculate each sentence
    int[] sentencesWidth = new int[sentences.length];
    //store max width
    int maxWidth = 0;
    for (int i = 0; i < sentences.length; i++) {
        textView.setText(sentences[i]);
        textView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
        sentencesWidth[i] = textView.getMeasuredWidth();
        if (sentencesWidth[i] > maxWidth) {
            maxWidth = sentencesWidth[i];
        }
    }
    //add space after each sentence if necessary
    for (int i = 0; i < sentences.length; i++) {
        int spaceNum = (maxWidth - sentencesWidth[i]) / slice;
        StringBuilder sb = new StringBuilder();
        for (int k = 0; k < spaceNum; k++) {
            sb.append(" ");
        }
        sentences[i] += sb.toString();
    }
    //rebuild String
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < sentences.length; i++) {
        sb.append(sentences[i]);
        if (i != sentences.length - 1) {
            sb.append("\n");
        }
    }
    return sb.toString();
}
