我有这段代码
public class MainActivity extends Activity {
TextView textview;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String hallo = "blabla " + "jojo " + "lol " + "\n" + "doj " + "drasl " + "\n";
InputStream is = new ByteArrayInputStream(hallo.getBytes());
BufferedReader in = new BufferedReader(new InputStreamReader(is));
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linearLayout);
String line;
try {
while ((line = in.readLine()) != null) {
String[] RowData = line.split(" ");
String eitt = RowData[0];
String tvo = RowData[1];
TextView textView = new TextView(this);
textView.setText(line);
linearLayout.addView(textView);
}
} catch (IOException e1) {
e1.printStackTrace();
}
}
}
使用此xml布局
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/linearLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
我想将字符串的这些部分插入到表格布局中,这样当我的文本片段被打印出来时,它们会出现在漂亮的列中。它的工作方式,它只是打印行的字符串行而不是将其放入列。同样非常重要的是要知道我不知道字符串中会有多少行,所以我不能只制作4个textview框,因为可能有50 og一百行,所以我需要制作一个表视图中的textview框的数量,其中i是行数
答案 0 :(得分:2)
尝试将setLayoutParams
添加到TextView
:
//Your code...
String line;
try {
while ((line = in.readLine()) != null) {
String[] RowData = line.split(" ");
String eitt = RowData[0];
String tvo = RowData[1];
TextView textView = new TextView(this);
textView.setText(line);
textView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT
,LayoutParams.WRAP_CONTENT));
linearLayout.addView(textView);
}
} catch (IOException e1) {
e1.printStackTrace();
}
//Your code...
