PowenKo, android, Tutorial 020-7, Layout, add other layout via code at the run-time
August 31, 2011 · 0 Comments
sample 1:
add TextView at the run time.
ArrayList<String> myList = getData();
for(String data : myList) {
LinearLayout layout = new LinearLayout(this);
layout.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
TextView textView = new TextView(this);
textView.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
textView.setText("hi!");
layout.addChild(textView);
parentPanel.addView(layout);
}
sample 2, add and remove the view at the run-time:
For ur requirement , u can use a single linear layout and add child views to it whenever u need a new View.
for example ,
LinearLayout parent = new LinearLayout ( context ); parent.setLayoutParams(width, height ); //width, height can be set as needed. parent.addView(myView , 0 );
When u have formed a new LinearLayout as the next View , it can be added as the child to the parent .
Now,
parent.addView(newLinearLayout, 0 );
You can remove the previous View that u had added to the parent first by calling
parent.removeViewAt(1);
because after the new child was added , the previous view would have now become the second (index = 1 ) child.
You can apply the above logic whenever u have to display a new View.
