Question

我有一个在垂直LinearLayout中创建3个textView的方法：

public LinearLayout CreateLayout() {

    LinearLayout aLap = new LinearLayout(this);

    LinearLayout.LayoutParams TextParams = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT);

    TextView txtName = new TextView(this);
    txtName.setText(result1);

    txtName.setLayoutParams(TextParams);
    txtName.setGravity(Gravity.CENTER);
    txtName.setPadding(20, 8, 20, 4);
    txtName.setTextSize(20);
    txtName.setTextColor(Color.parseColor("#000000"));

    TextView txtTime = new TextView(this);
    txtTime.setText(result2);
    txtTime.setLayoutParams(TextParams);
    txtTime.setGravity(Gravity.CENTER);
    txtTime.setTextSize(20);
    txtTime.setPadding(20, 4, 10, 4);
    txtTime.setTextColor(Color.parseColor("#000000"));

    android.view.ViewGroup.LayoutParams Params = new ViewGroup.LayoutParams(
            android.view.ViewGroup.LayoutParams.MATCH_PARENT, 150);

    TextView rep = new TextView(this);
    String Rep = sharedPrefs.getString("R_PREFS", "2");

    rep.setLayoutParams(TextParams);
    rep.setGravity(Gravity.CENTER);
    rep.setTextSize(20);
    rep.setPadding(20, 4, 10, 4);
    rep.setTextColor(Color.parseColor("#000000"));
    rep.setText("Test: " + Rep);

    aLap.setLayoutParams(Params);
    aLap.setBackgroundResource(R.drawable.bg);
    aLap.setOrientation(LinearLayout.VERTICAL);
    aLap.setPadding(3, 3, 3, 3);
    aLap.addView(txtName);
    aLap.addView(txtTime);
    aLap.addView(rep);

    return aLap;

}

我使用垂直布局，因为我希望textViews放在彼此之下。现在我希望将ImageView放置在此textView的右侧并垂直居中。这可能吗？

Answer 1

使用单 LinearLayout无法获得所需的输出。我建议你使用RelativeLayout。它更灵活。您可以通过向视图添加规则，在所需位置向RelativeLayout添加更多子视图。查看此帖子，了解在运行时使用Relative Layout时如何添加规则：How to lay out Views in RelativeLayout programmatically?。

Answer 2

<LinearLayout  orientation="horizontal">
  <LinearLayout orientation="vertical">
    <TextView view1/>
    <TextView view1/>
    <TextView view1/>
  </LinearLayout>
  <ImageView height=fill_parent scaleType="center"/>
</LinearLayout>

或多或少是我想要的
