代码语言:javascript复制
</pre>作为一个初学者,对好多界面都感兴趣。 所以就动手慢慢做,然后写为博客。第一个简单的例子就是仿照微信的删除联系人节目。<p></p><p></p><p>1: 先看布局文件(需要注意: 我的布局文件里好多参数都是写死的,只是举例说明。 )</p><p></p><p></p><pre name="code" class="html"><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="${relativePackage}.${activityClass}" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="删除联系人"
android:textColor="#000000"
android:textSize="24dp"
android:padding="15dp"
/>
</LinearLayout>
<TextView
android:layout_weight="2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:text="将联系人***删除,将同时删除与该联系人的聊天记录"
android:textSize="20dp"
android:textColor="#000000"
/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
>
<Button
android:id="@ id/btn_cancle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="取消"
android:textColor="#4682B4"
android:background="#FFFFFF"
android:layout_marginBottom="5dp"
<span style="white-space:pre"> </span>android:layout_toLeftOf="@ id/btn_ok"
/>
<Button
android:id="@ id/btn_ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="删除"
android:layout_marginBottom="5dp"
android:textColor="#FF0000"
android:layout_marginRight="10dp"
android:background="#FFFFFF"
android:layout_alignParentRight="true"
/>
</RelativeLayout>
</LinearLayout>
2:下面贴出Activity代码(我用的是一个button按下后, 会弹出删除联系人的dialog)
代码语言:javascript复制 Button button = (Button)findViewById(R.id.btn_delete);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog = new Dialog(DeletePeopleActivity.this);
LayoutInflater inflater = LayoutInflater.from(DeletePeopleActivity.this);
View view = inflater.inflate(R.layout.activity_delete_people, null);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(view);
dialog.show();
Button delteButton = (Button)view.findViewById(R.id.btn_ok);
delteButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(DeletePeopleActivity.this, "Delete!", 3000).show();
dialog.dismiss();
}
});
Button canclyeButton = (Button)view.findViewById(R.id.btn_cancle);
canclyeButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(DeletePeopleActivity.this, "Cancle!", 3000).show();
dialog.dismiss();
}
});
