I'm trying to implement tags through textview. I type in something to a EditText and press a button to add a tag. I'm programmatically adding padding and rectangle background to the textview but the padding setting does not have any effect. How do I add the padding such that it works?
public void tag_it_callback (View view) {
Log.v("actv", "tag it callback");
LinearLayout main_layout = (LinearLayout) findViewById(R.id.main_layout);
TextView tv = new TextView(this);
tv.setText( ((EditText) findViewById(R.id.textfield)).getText() );
main_layout.addView(tv);
transform_tag(tv);
}
public void transform_tag(TextView tv) {
// set padding and background
int padding = 10;
tv.setPaddingRelative(20, 20, 20, 20);
tv.setPadding(20, 20, 20, 20);
tv.setBackgroundResource(R.drawable.border);
// set layout width and height
LayoutParams params= (LayoutParams) tv.getLayoutParams();
Log.v("actv", "params "+params);
if ( params != null ) {
params.width=LayoutParams.WRAP_CONTENT;
params.height=LayoutParams.WRAP_CONTENT;
} else {
params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
}
tv.setLayoutParams(params)
}
border.xml goes like this
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#FF0000" />
<corners
android:bottomLeftRadius="8dp"
android:bottomRightRadius="8dp"
android:topLeftRadius="8dp"
android:topRightRadius="8dp" />
</shape>
</item>
<item android:left="5dp" android:right="5dp" android:top="5dp" android:bottom="5dp">
<shape android:shape="rectangle">
<solid android:color="#000000" />
</shape>
</item>
</layer-list>"`<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#FF0000" />
<corners
android:bottomLeftRadius="8dp"
android:bottomRightRadius="8dp"
android:topLeftRadius="8dp"
android:topRightRadius="8dp" />
</shape>
</item>
<item android:left="5dp" android:right="5dp" android:top="5dp" android:bottom="5dp">
<shape android:shape="rectangle">
<solid android:color="#000000" />
</shape>
</item>
</layer-list>`
I finally found the problem I have to set the background first before setting the padding. Setting the padding then setting the background doesn't work
// does not work
tv.setPadding(20, 20, 20, 20);
tv.setBackgroundResource(R.drawable.border);
// works
tv.setBackgroundResource(R.drawable.border);
tv.setPadding(20, 20, 20, 20);
