I have below layout in xml. But I want to add few more similar rows(RelativeLayouts one below another) dynamically with same layout. I've tried the below code, but all the values are overlapping.
Also I don't know how to add textview one below another programmatically.
Any help in solving this would be helpful. Thanks in advance.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ccc">
<LinearLayout
android:id="@+id/searchResultsLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:background="#fff"
android:layout_marginStart="20dp"
android:layout_marginEnd="20dp"
android:layout_height="100dp"
android:padding="6dip" >
<TextView
android:id="@+id/firstLine"
android:layout_width="fill_parent"
android:layout_height="26dp"
android:ellipsize="marquee"
android:text="Ali Connors"
android:textSize="16sp" />
<TextView
android:id="@+id/secondLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/firstLine"
android:gravity="center_vertical"
android:text="Brunch this weekend?"
android:textSize="12sp" />
<TextView
android:id="@+id/rightTime"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:text="15m"
android:textSize="16sp" />
</RelativeLayout>
</LinearLayout>
</LinearLayout>
代码:
LinearLayout ll = (LinearLayout) findViewById(R.id.searchResultsLayout);
for (int i = 0; i <1; i++) {
RelativeLayout row= new RelativeLayout(this);
RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
relativeParams.setMargins(20, 5, 20, 5);
row.setBackgroundColor(Color.parseColor("#ffffff"));
ll.setLayoutParams(relativeParams);
TextView name = new TextView(this);
TextView time = new TextView(this);
TextView dest = new TextView(this);
name.setText("Name");
time.setText("9hrs");
dest.setText("Destination");
row.addView(name);
row.addView(time);
row.addView(dest);
ll.addView(row,i);
}
推荐答案
LinearLayout ll = (LinearLayout) findViewById(R.id.searchResultsLayout);
ll.setOrientation(LinearLayout.VERTICAL);
for (int i = 0; i <1; i++) {
RelativeLayout row= new RelativeLayout(this);
RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
relativeParams.setMargins(20, 5, 20, 5);
row.setBackgroundColor(Color.parseColor("#ffffff"));
ll.setLayoutParams(relativeParams);
TextView name = new TextView(this);
TextView time = new TextView(this);
TextView dest = new TextView(this);
final RelativeLayout.LayoutParams paramsval =
new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams
(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
name.setText("Name");
name.setId(View.generateViewId());
time.setText("9hrs");
dest.setText("Destination");
time.setLayoutParams(layoutParams);
row.addView(time);
row.addView(name);
paramsval.addRule(RelativeLayout.BELOW,name.getId());
dest.setLayoutParams(paramsval);
row.addView(dest);
ll.addView(row,i);
}
