如何获得onClickListener（）自定义动作条事件

问题描述

限时删除！！

我正在开发中，我必须让的onClick（）活动的点击动作条自定义视图的应用。到目前为止，我能够实现以下布局。

I'm developing an application in which I have to get onClick() event on click of actionbar custom view. So far I'm able to achieve the following layout.

下面是我的code为实现这一目标：

Here is my code for achieving this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);

    getActionBar().setCustomView(R.layout.custom_image_button);
    getActionBar().setDisplayOptions(
            ActionBar.DISPLAY_SHOW_HOME | ActionBar.DISPLAY_SHOW_CUSTOM);

}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {

    case android.R.id.home:
        Toast.makeText(getApplicationContext(), "Clicked on ActionBar",
                Toast.LENGTH_SHORT).show();

    default:
        return super.onOptionsItemSelected(item);
    }
}

下面是我的custom_image_button布局：

Here is my custom_image_button layout:

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

<FrameLayout
    android:id="@+id/frame_layout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true" >

    <TextView
        android:id="@+id/points"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_marginRight="10dp"
        android:layout_marginTop="5dp"
        android:background="@drawable/points_yellow"
        android:gravity="center"
        android:paddingLeft="20dp"
        android:textColor="#887141"
        android:textIsSelectable="false"
        android:textSize="22sp"
        android:textStyle="bold" >
    </TextView>

    <ImageView
        android:id="@+id/badge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="top|right"
        android:layout_marginRight="5dp"
        android:layout_marginTop="0dp"
        android:src="@drawable/badge_notification" >
    </ImageView>
</FrameLayout>

</RelativeLayout>

我是想对自定义布局点击监听器。为此我曾尝试以下code：

I was trying to have a click listener on the custom layout. For that I have tried the following code:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);

    getActionBar().setCustomView(R.layout.custom_image_button);
    getActionBar().setDisplayOptions(
            ActionBar.DISPLAY_SHOW_HOME | ActionBar.DISPLAY_SHOW_CUSTOM);

    final LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View v = inflater.inflate(R.layout.custom_image_button, null);

    frameLayout = (FrameLayout) v.findViewById(R.id.frame_layout);

    frameLayout.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Toast.makeText(getApplicationContext(), "Clicked on 1",
                    Toast.LENGTH_SHORT).show();
            return false;
        }
    });
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {

    case android.R.id.home:
        Toast.makeText(getApplicationContext(), "Clicked on ActionBar",
                Toast.LENGTH_SHORT).show();

    default:
        return super.onOptionsItemSelected(item);
    }
}

}

但是，我无法得到自定义图像的onClick（）事件。什么我做错了，请指导。

But, I'm unable to get onClick() event on the custom image. What I'm doing wrong here, please guide.

任何形式的帮助将是AP preciated。

Any kind of help will be appreciated.

推荐答案

所以，你必须添加安卓的onClick =clickEvent在动作条自定义布局文件

after in Inflater its just like view in layout file

so, you have to add android:onClick="clickEvent" in ActionBar custom layout file

我mainactivity：

my mainactivity:

package com.example.testdemo;

import android.annotation.SuppressLint;
import android.app.ActionBar;
import android.app.Activity;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.Toast;

public class MainActivity extends Activity {

    private View viewList;
    private Dialog dialogMarketList;
    String a[] = { "a", "aa" };
    private View header;

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ActionBar actionBar = getActionBar();
        actionBar.setDisplayShowTitleEnabled(false);
        actionBar.setDisplayUseLogoEnabled(false);
        actionBar.setDisplayHomeAsUpEnabled(false);
        actionBar.setDisplayShowCustomEnabled(true);
        View cView = getLayoutInflater().inflate(R.layout.header, null);
        actionBar.setCustomView(cView);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    public void clickEvent(View v) {
        if (v.getId() == R.id.button1) {
            Toast.makeText(MainActivity.this, "you click on button1",
                    Toast.LENGTH_SHORT).show();
        }

        if (v.getId() == R.id.button2) {
            Toast.makeText(MainActivity.this, "you click on button2",
                    Toast.LENGTH_SHORT).show();
        }

        if (v.getId() == R.id.textView1) {
            Toast.makeText(MainActivity.this, "you click on textView1",
                    Toast.LENGTH_SHORT).show();
        }
    }
}

我的布局header.xml

my layout header.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="horizontal"
    android:weightSum="3" >

    <Button
        android:id="@+id/button1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:onClick="clickEvent"
        android:text="Button 1" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:onClick="clickEvent"
        android:gravity="center"
        android:textColor="#FFFFFF"
        android:text="My action bar"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <Button
        android:id="@+id/button2"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:onClick="clickEvent"
        android:text="Button 2" />

</LinearLayout>
