Zvese zvinhu zvinoonekwa pachiratidziro che Android application maonero. Kubva pane zvakasarudzika zvinhu senge zvinyorwa kana mabhatani, kune midziyo yakaita semapoka emaonero. Iyi nhaurwa yakaoma zvikuru nekuda kwehuwandu hwehuwandu hwakabatanidzwa, uye kuongorora mikana iripo zvizere, zvinokurudzirwa kwazvo kuenda ku zvinyorwa zvepamutemo. Muchidzidzo ichi tichaongorora zvinhu zvakanyanyo shandiswa, kusanganisira mapoka emaonero uye zvimwe zvakakosha zvinhu
Wona Mapoka
- LinearLayout
- Mapoka ezvinhu mumutsara mumwe chete, anogona kuve akamira kana akatwasuka.
- RelativeLayout
- Izvo zvinhu zvakarongedzwa zvine hukama kune mumwe nemumwe uye kumahombekombe. Iyo ndiyo inonyanya kusanduka, uye yakanyanya kushandiswa.
- MupumburuVona
- Inoshandiswa pakuona zvisina kukodzera pachiratidziri. Inogona kungova nekutarisa kumwe chete kana boka remaonero, uye inongowedzera mipumburu yekutsikisa.
- TafuraLayout
- Boka zvinhu mumitsara nemakoramu. Ine zvinhu zveTafuraRow, izvo zvine zvimiro zveimwe neimwe sero.

Isu takaona pamberi pekuti TextView inoshanda sei, nekuti inongofanirwa kusanganisira zvinyorwa. Mu zvinyorwa zvepamutemo tinogona kuwana zvimwe zvemberi sarudzo senge kusiyanisa font, saizi saizi, ruvara, uye zvimwe zvakawanda.
Mabhatani ari eanonyanya kufarira, nekuti neimwe nzira isu tinofanirwa kusanganisa chiito navo. Tichaona nzira mbiri. Mune imwe, isu tinobatanidza zvakananga chiito mune kodhi yechiitiko chedu:
Bhatani bhatani = (Bhatani) tsvagaViewById (R.id.button1);
button.setOnClickListener (new View.OnClickListener () {
public void onClick (Tarisa v) {
DisplayToast ("Wakamanikidza bhatani");
