Question

请让我举一个非常简单的例子,在某个职位上将儿童观点列入<条码>。

举例来说,为了反映以下的《公约》:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="107dp"
    android:layout_marginTop="103dp"
    android:text="Large Text"
    android:textAppearance="?android:attr/textAppearanceLarge" />

我不理解如何创建适当的<代码>RelativeLayout.LayoutParams。

Answer 1

下面是你开始的榜样,酌情填写其余部分:

TextView tv = new TextView(mContext);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
    ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
params.leftMargin = 107
...
mRelativeLayout.addView(tv, params);

The docs for RelativeLayout. LayoutParams和建筑商是:here。

Answer 2

首先,你应该向你们的亲爱的Layout说相对的Layout1。

RelativeLayout mainLayout = (RelativeLayout) findViewById(R.id.relativeLayout1);
TextView mTextView = new TextView(context);
mTextView.setText("Dynamic TextView");
mTextView.setId(111);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
params.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
mainLayout.addView(mTextView, params);
