主要還是在製作 9-Patch 圖片,程式只是例行作業。
NinePatchBtnActivity
public class NinePatchBtnActivity extends Activity implements OnClickListener {
private boolean isNormal;
private List<Button> btnList = new ArrayList<Button>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button normalBtn = (Button) this.findViewById(R.id.normal);
Button widthBtn = (Button) this.findViewById(R.id.width);
Button heightBtn = (Button) this.findViewById(R.id.height);
this.btnList.add(normalBtn);
this.btnList.add(widthBtn);
this.btnList.add(heightBtn);
for (Button btn : this.btnList) {
btn.setOnClickListener(this);
}
}
@Override
public void onClick(View v) {
TextView tv = (TextView) this.findViewById(R.id.tv);
if (this.isNormal) {
this.setBackgroundResource(R.drawable.bg);
tv.setText("9-Patch");
this.isNormal = false;
}
else {
this.setBackgroundResource(R.drawable.bg_n);
tv.setText("Normal");
this.isNormal = true;
}
}
private void setBackgroundResource(int resId) {
for (Button btn : this.btnList) {
btn.setBackgroundResource(resId);
}
}
}
