Question

我有一个编辑文本和按钮。默认情况下，此按钮不可见。

当我点击编辑文本时，它会显示soft-keyborad，此按钮可见。我抓住了编辑文本的点击事件，并设置此按钮是可见的。但是，直到我点击第二个编辑文本（显示在soft-keyborad中）才能看到它

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
        android:focusable="true" 
    android:focusableInTouchMode="true" 
android:orientation="vertical" >

<EditText
    android:id="@+id/editText1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:ems="10" >

</EditText>

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_below="@+id/editText1"
    android:text="Button" />

</RelativeLayout>

代码

public class anr extends Activity {
InputMethodManager imm; 
/** Called when the activity is first created. */ 

@Override 
public void onCreate(Bundle savedInstanceState) { 
imm = (InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE); 
super.onCreate(savedInstanceState); 
setContentView(R.layout.testaaa); 

final Button btn = (Button)this.findViewById(R.id.button1);
btn.setVisibility(View.INVISIBLE);

final EditText txtSearch = (EditText)this.findViewById(R.id.editText1); 
txtSearch.setOnClickListener(new OnClickListener() { 

public void onClick(View v) { 
// TODO Auto-generated method stub 
txtSearch.setFocusable(true);//(false); 
txtSearch.setFocusableInTouchMode(true); 
txtSearch.requestFocus(); 
btn.setVisibility(View.VISIBLE);
} 
}); 

txtSearch.setOnKeyListener(new OnKeyListener() { 

public boolean onKey(View v, int keyCode, KeyEvent event) { 
// TODO Auto-generated method stub 
if ((event.getAction() == KeyEvent.ACTION_DOWN) && 
(keyCode == KeyEvent.KEYCODE_ENTER)) 
{ 
    btn.setVisibility(View.INVISIBLE);
    hideSoftKeyboard(v); 
    txtSearch.clearFocus(); 
} 



return false; 
}}); 

} 
public void hideSoftKeyboard (View view) { 

imm.hideSoftInputFromWindow(view.getWindowToken(), 0); 
} 
}

Answer 1

请为您的编辑文字设置触控监听器。

并放置你的onclick方法，即

txtSearch.setFocusable(true);
txtSearch.setFocusableInTouchMode(true); 
txtSearch.requestFocus(); 
btn.setVisibility(View.VISIBLE);

那里。：）

Answer 2

试试这段代码......

txtSearch.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
btn.setVisibility(View.INVISIBLE);
hideSoftKeyboard(v); 
txtSearch.clearFocus(); 
}

单击编辑文本时无法显示按钮
