TextView onClick()不起作用 [英] TextView onClick() not working
问题描述
这是我的 main.xml 代码
here's my code for main.xml
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout
android:id="@id/container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<include layout="@layout/tabs" />
<ScrollView
android:fillViewport="true"
android:scrollbars="@null"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<LinearLayout
android:paddingTop="10dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<!-- first text_view -->
<TextView
android:background="@color/grey"
android:textColor="@color/white"
android:text="@string/category"
android:id="@+id/category1"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_marginTop="65dp"
android:textSize="17dp"
android:typeface="serif"/>
<!-- first horizontal_scrollview -->
<HorizontalScrollView
android:scrollbars="@null"
android:id="@+id/horizontalScrollView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout android:id="@+id/linearLayout1"
android:orientation="horizontal"
android:visibility="visible"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
<!-- image_view should be here -->
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
</ScrollView>
</RelativeLayout>
</merge>
这是我的 tabs.xml 代码
here's my code for tabs.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#333333">
<TextView
android:textColor="@color/gradient_green"
android:id="@+id/viewall"
android:layout_width="85dp"
android:layout_height="25dp"
android:layout_marginLeft="10dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:textSize="17dp"
android:textStyle="bold"
android:text="@string/view_all"
android:onClick="onClick"
android:focusable="false"
android:clickable="true" />
<TextView
android:textColor="@color/white"
android:id="@+id/pic"
android:layout_width="45dp"
android:layout_height="25dp"
android:layout_alignParentTop="true"
android:layout_toRightOf="@+id/viewall"
android:textSize="17dp"
android:textStyle="bold"
android:text="@string/pic"
android:onClick="onClick"
android:focusable="false"
android:clickable="true" />
</RelativeLayout>
这是 Main.java 中的代码:
and here's the code inside the Main.java:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView all = (TextView) this.findViewById(R.id.viewall);
TextView pic = (TextView) this.findViewById(R.id.pic);
all.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
TextView all = (TextView) findViewById(R.id.viewall);
TextView pic = (TextView) findViewById(R.id.pic);
Toast.makeText(Main.this, "VIEW ALL", Toast.LENGTH_SHORT).show();
all.setTextColor(getResources().getColorStateList(R.color.gradient_green));
pic.setTextColor(getResources().getColorStateList(R.color.white));
}
});
pdf.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
TextView all = (TextView) findViewById(R.id.viewall);
TextView pic = (TextView) findViewById(R.id.pic);
Toast.makeText(Main.this, "VIEW ALL", Toast.LENGTH_SHORT).show();
all.setTextColor(getResources().getColorStateList(R.color.white));
pic.setTextColor(getResources().getColorStateList(R.color.gradient_green));
}
});
}
所以,如果我将 Main.class 或 Main.java 中的 setContentView() 设置为 setContentView(R.layout.tabs) 而不是 setContentView(R.layout.main),onClick() 有效,我应该怎么做阻止 onClick() 不起作用的代码有什么问题或有什么问题?
so, if I set the setContentView() in the Main.class or Main.java as setContentView(R.layout.tabs) instead of setContentView(R.layout.main), the onClick() works, what should I do or what's wrong with my code that hinders onClick() not to work?
推荐答案
使用这些
all = (TextView) this.findViewById(R.id.viewall);
pdf = (TextView) this.findViewById(R.id.pic);
在创建然后设置
all.setOnclickListener(this) 也在 oncreate() 方法中.当它显示错误时执行 onClicklistener.它会像魅力一样发挥作用.
all.setOnclickListener(this) in oncreate() method too.Implement onClicklistener when it will show error. it will work like a charm.
已编辑
TextView btn=(TextView) findViewById(R.id.accInfo);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//DO you work here
}
});
将 Clicklistenner 设置为 TextView 将自动使其可点击,因此无需
android:clickable="true"
