As with padding, the price of any of those is a dimension—a mix of a unit of degree and a count number, equivalent to 5px for five pixels. LinearLayout instance Let’s examine an instance (Containers/Linear) that exhibits LinearLayout homes set either within the XML format dossier and at runtime. here's the format: CHAPTER 10: operating with bins be aware that we've got a LinearLayout wrapping RadioGroup units. RadioGroup is a subclass of LinearLayout, so our instance demonstrates nested packing containers as though they have been all LinearLayout bins. the head RadioGroup units up a row (android:orientation = "horizontal") of RadioButton widgets. The RadioGroup has 5dip of padding on both sides, setting apart it from the opposite RadioGroup, the place dip stands for density-independent pixels (think of them as traditional pixels for now—we gets into the excellence later within the book). The width and top are either set to wrap_content, so the radio buttons will absorb in basic terms the distance that they want. the ground RadioGroup is a column (android:orientation = "vertical") of 3 RadioButton widgets. back, we now have 5dip of padding on either side and a common top (android:layout_height = "wrap_content"). despite the fact that, we now have set android:layout_width to be fill_parent, that means the column of radio buttons claims the complete width of the monitor. to regulate those settings at runtime according to consumer enter, we'd like a few Java code: package deal com. commonsware. android. linear; import import import import import import import android. app. task; android. os. package deal; android. view. Gravity; android. textual content. TextWatcher; android. widget. LinearLayout; android. widget. RadioGroup; android. widget.

OnCheckedChangeListener { orientation; gravity; @Override public void onCreate(Bundle icicle) { tremendous. onCreate(icicle); setContentView(R. format. main); orientation=(RadioGroup)findViewById(R. identification. orientation); orientation. setOnCheckedChangeListener(this); gravity=(RadioGroup)findViewById(R. identity. gravity); gravity. setOnCheckedChangeListener(this); } public void onCheckedChanged(RadioGroup crew, int checkedId) { swap (checkedId) { case R.
