android - textview 不显示文本(一个 TextView 将另一个 TextView 推离屏幕很远)

Question

现在 textview 显示如果我将滚动到底部的语句。看起来 promis textview 变大了。有办法解决吗？

星号下的所有内容都是 promis textview 的一部分。它是一个带有多个换行符的字符串 另一个截图

生成 promise 的代码

prm = doc.getElementsByTagName("promise");
            for (int j = 0; j < prm.getLength(); j++) {
                prom += parser.getValue(e, KEY_PROMISES, j) + "\n";

            }
            prom.substring(0,prom.lastIndexOf('\n'));

布局

我的应用的 Activity

public class SingleMenuItemActivity  extends Activity {


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.candidate);
        Log.d("here ?", "No ");
        int loader = R.drawable.loader;
        // getting intent data
        Intent in = getIntent();
        Log.d("here ?", "No ");
        // Get XML values from previous intent
        String name = in.getStringExtra("name");
        Log.d("Name ", name);
        Log.d("here ?", "No ");
        DatabaseHandler db = new DatabaseHandler(this);
        Log.d("here ?", "No ");
        Candidate p = db.getCandidate(name);
        Log.d("Did i take candidate? ", "yea ");
        db.close();
        Log.d("Statement", p.get_statment());
        // Displaying all values on the screen
        TextView lblName = (TextView) findViewById(R.id.name);
        TextView lblOffice = (TextView) findViewById(R.id.office);
        TextView lblPromise = (TextView) findViewById(R.id.promises);
        TextView lblStatement = (TextView) findViewById(R.id.statement);
        ImageView lblFace = (ImageView) findViewById(R.id.face);
        RatingBar lblRating = (RatingBar) findViewById(R.id.ratingBar1);
        ImageLoader imgLoader = new ImageLoader(this);
        lblName.setText(p.get_name());
        lblOffice.setText(p.get_office());
        lblPromise.setText(p.get_promises());
        lblStatement.setText(p.get_statment());
        lblRating.setRating(p.get_ranking());
        imgLoader.DisplayImage(p.get_photograph(), loader, lblFace);

    }
}

logcat 说 p.get_statment() 有适当的值(value)

If, like me, you think that the University's reputation is being dragged down by lecturers who have little or no regard for fashion and are content to wear ill-fitting or patched clothes then vote for me: the stylish choice.

Answer 1

看起来您的 RatingBar 覆盖了您的 statement TextView:

<RatingBar
    android:layout_above="@+id/statement"
    ... />

也许你的意思是 layout_below？

此外，您的 promises TextView 的上边距非常大，它可能会将 statement TextView 推离屏幕底部:

<TextView
    android:id="@+id/promises"
    android:layout_marginTop="124dp"
    ... />

添加
显然，在您的 promises TextView 末尾还有一些换行符。如果您无法从源中删除这些字符，您可以使用 trim() :

prom = prom.trim();
