我正在务实地创建一些按钮。使用来自 2 个不同活动的相同代码，按钮触发不适用于其中一个活动。对于我必须忽略的内容，我感到有些困惑。
public class Home_Page_Activity extends Activity {
JSONArray nameArray;
JSONArray valArray;
String[] arrayButtonTitles;
String font;
Context context = null;
LinearLayout.LayoutParams params_textview;
LinearLayout.LayoutParams params_button;
LinearLayout.LayoutParams params_linearlayout;
LinearLayout home_page_layout;
OnClickListener myListener;
Typeface face;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.home_page_activity);
WebView wv_Welcome_Message = (WebView) findViewById(R.id.wv_Welcome_Message);
context = getApplicationContext();
params_linearlayout = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT, 1.0f);
params_linearlayout.gravity = Gravity.CENTER;
// Set Font
font = "fonts/aescrawl.ttf";
face = Typeface.createFromAsset(getAssets(), font);
// Reference Layout
home_page_layout = (LinearLayout) findViewById(R.id.home_page_layout);
// Set Layout Parameters for XML Elements. (Height, Width,
// Weight,Padding)
params_button = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, 32, 1.0f);
params_button.setMargins(10, 0, 10, 30);
// Load webview if there is connectivity
if (Repeatables.isNetworkAvailable(context) == true) {
new InitTask().execute();
} else {
wv_Welcome_Message.setVisibility(View.GONE);
}
String[] arrayButtonTitles = { "Sub 1", "Sub 2", "Final 1", "Final 2",
"Category 5", "Category 6", "Category 7", "Category 8",
"Category 9", "Category 10" };
Load_Main_Menu(arrayButtonTitles);
myListener = new OnClickListener() {
public void onClick(View v) {
Object tag = v.getTag();
// Do something depending on the value of the tag
Log.e("TAG","Button "+tag+" pushed");
if("0".equals(tag.toString())){
Log.e("TAG","Hello 1");
}else if("21".equals(tag.toString())){
Intent i = new Intent(getApplicationContext(), Sub_Menu_Categories_Main_Activity.class);
i.putExtra("whatSubMenuToLoad","none");
i.putExtra("whatScreenTypeToLoad","FINALCATEGORY");
i.putExtra("categoryId","313");
startActivity(i);
}
}
};
}
// Build Home Page XML Layout
public void Load_Main_Menu(String[] buttons) {
arrayButtonTitles = buttons;
int numberOfButtons = arrayButtonTitles.length;
LinearLayout[] ll = new LinearLayout[numberOfButtons];
// Add Elements to Layout
for (int i = 0; i < numberOfButtons; i++) {
Button btn = new Button(this);
btn.setText(arrayButtonTitles[i]);
btn.setTag(i);
btn.setOnClickListener(myListener);
btn.setTypeface(face);
btn.setTextSize(18);
btn.setTextColor(context.getResources().getColor(
R.color.all_button_font_color));
btn.setBackgroundResource(R.drawable.category_button_background_shape);
if (i % 2 == 0) {
ll[i] = new LinearLayout(this);
ll[i].setOrientation(LinearLayout.HORIZONTAL);
ll[i].addView(btn, params_button);
home_page_layout.addView(ll[i], params_linearlayout);
} else {
ll[i - 1].addView(btn, params_button);
}
}
}
}
