【问题描述】:
我正在做一个应用程序,例如当我点击图像时(它是一个 searchView)
搜索板打开!
看起来像
但这里会显示默认的搜索图标(放大镜),但一旦输入一些文本,它就会消失
但我不希望即使第一次点击图像也显示放大镜
这里我没有使用任何 xml 文件
我的代码是
public class MainActivity extends Activity {
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
RelativeLayout relative = new RelativeLayout(this);
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
relative.setLayoutParams(params);
setContentView(relative);
SearchView searchView = new SearchView(this);
traverseView(searchView, 0);
// searchView.setIconifiedByDefault(false);
LayoutParams searchViewparams = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
// searchViewparams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
searchView.setLayoutParams(searchViewparams);
relative.addView(searchView);
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@SuppressLint("NewApi")
private void traverseView(View view, int index) {
if (view instanceof SearchView) {
SearchView v = (SearchView) view;
for(int i = 0; i < v.getChildCount(); i++) {
traverseView(v.getChildAt(i), i);
}
} else if (view instanceof LinearLayout) {
LinearLayout ll = (LinearLayout) view;
for(int i = 0; i < ll.getChildCount(); i++) {
traverseView(ll.getChildAt(i), i);
}
} else if (view instanceof EditText) {
((EditText) view).setTextColor(Color.GREEN);
((EditText) view).setHintTextColor(Color.BLACK);
} else if (view instanceof TextView) {
((TextView) view).setTextColor(Color.BLUE);
} else if (view instanceof ImageView) {
((ImageView) view).setImageResource(R.drawable.ic_launcher);
} else {
Log.v("View Scout", "Undefined view type here...");
}
}
}
