INPUT_METHOD_SERVICE); if (imm. isActive () {imm. hideSoftInputFromWindow (v. getApplicationWindowToken (), 0);} listener. onSearchClick (v);} return false;} public interface OnSearchClickListener {void onSearchClick (View view );}}

3. style

</Style> <style name = "StyleEditText"> <item name = "android: layout_width"> match_parent </item> <item name = "android: layout_height "> wrap_content </item> <item name =" android: background "> @ drawable/bg_search_bar </item> <item name =" android: drawablePadding "> 5dp </item> <item name =" android: gravity "> center_vertical </item> <item name =" android: imeOptions "> actionSearch </item> <item name =" android: drawableLeft "> @ drawable/icon_search </item> <item name =" android: padding "> 5dp </item> <item name =" android: singleLine "> true </item> <item name =" android: textColorHint "> @ color/gray </item> <item name =" android: textSize "> 16sp </item> <item name =" android: hint "> Search </item> </style>

private IconCenterEditText search_et;

search_et = (IconCenterEditText) findViewById(R.id.search_et);

Search_et.setOnSearchClickListener (new OnSearchClickListener () {@ Override public void onSearchClick (View view) {// TODO Auto-generated method stub String texts = search_et.getText (). toString (). trim (); if ("". equals (texts) {ToastUtil. showToast ("Enter the content you want to search for");} else {// jump based on your text content

                    Intent intent = new Intent(context,                            SearchWordActivity.class);                    // intent.putExtra("searchMode", 1);                    intent.putExtra("searchWord", texts);                    context.startActivity(intent);                }            }        });
