I am triying to use dynamic layout for comment part of my project but when i settext of textview dynamicly the output only appears in top of the screen. And it puts the output over the other outputs
RelativeLayout ll=(RelativeLayout) findViewById(R.id.rl);
for(int i = 0; i < 20; i++) {
TextView cb = new TextView(this);
cb.setText("YORUMLAR"+yorum[0]+i);
cb.setTextSize(30);
ll.addView(cb);
}
So how can i put the output on the bottom of the screen linearly.
You should use LinearLayout
to automatically add one TextView
after another.
Assuming you can't live without RelativeLayout
, you'll need to dynamically generate ids for all TextView
you create in order to put one view under another. Here is example:
public class HelloWorld extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity);
RelativeLayout layout = (RelativeLayout)findViewById(R.id.layout);
Random rnd = new Random();
int prevTextViewId = 0;
for(int i = 0; i < 10; i++)
{
final TextView textView = new TextView(this);
textView.setText("Text "+i);
textView.setTextColor(rnd.nextInt() | 0xff000000);
int curTextViewId = prevTextViewId + 1;
textView.setId(curTextViewId);
final RelativeLayout.LayoutParams params =
new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.BELOW, prevTextViewId);
textView.setLayoutParams(params);
prevTextViewId = curTextViewId;
layout.addView(textView, params);
}
}
}
You've to provide the location of your newly added view. As @Adinia said, with no position, it will be aligned to the top by default. So you can use the following code to do it with RelativeLayout;
RelativeLayout containerLayout = (RelativeLayout) findViewById(R.id.container);
for (int i = 0; i < 20; i++) {
TextView dynaText = new TextView(this);
dynaText.setText("Some text " + i);
dynaText.setTextSize(30);
// Set the location of your textView.
dynaText.setPadding(0, (i * 30), 0, 0);
containerLayout.addView(dynaText);
}
If you want to show multiple textviews one after the other, then you should go with LinearLayout.
You may also add Dynamic textview to relative layout. Here with i have attached some code this may help you.
RelativeLayout ll=(RelativeLayout) findViewById(R.id.rl);
for(int i = 0; i < 20; i++)
{
TextView cb = new TextView(this);
cb.setText("YORUMLAR"+yorum[0]+i);
cb.setTextSize(30);
cb.setId(2000+i);
RelativeLayout.LayoutParams TextViewLayoutParams = new RelativeLayout.LayoutParams(100,100);
if (i != 0 )DispViewLayoutParams.addRule(RelativeLayout.BELOW, 2000 - (i-1));
ll.addView(cb,TextViewLayoutParams);
}
