Android自定义顶部标题栏

本文实例为大家分享了Android自定义顶部标题栏展示的具体代码，供大家参考，具体内容如下

思路及实现步骤

1.定义标题栏布局
2.自定义TitleActivity控制标题栏按钮监听
3.在TitleActivity中实现标题栏以下内容切换

首先定义标题栏

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/layout_titlebar"
  android:layout_width="match_parent"
  android:layout_height="52dp"
  android:background="#ed4255" > 

  <TextView
    android:id="@+id/text_title"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:ellipsize="marquee"
    android:gravity="center_horizontal|center"
    android:singleLine="true"
    android:text="标题栏"
    android:textColor="#ffffffff"
    android:textSize="20dp" /> 

  <Button
    android:id="@+id/button_backward"
    android:layout_width="60dp"
    android:layout_height="match_parent"
    android:background="@drawable/title_button_selector"
    android:drawableLeft="@drawable/back_arrow"
    android:drawablePadding="6dp"
    android:ellipsize="end"
    android:gravity="center"
    android:onClick="onClick"
    android:paddingLeft="5dp"
    android:singleLine="true"
    android:text="返回"
    android:textColor="#ffffffff"
    android:textSize="18dp"
    android:visibility="invisible" /> 

  <Button
    android:id="@+id/button_forward"
    android:layout_width="60dp"
    android:layout_height="match_parent"
    android:layout_alignParentRight="true"
    android:background="@drawable/title_button_selector"
    android:drawablePadding="6dp"
    android:ellipsize="end"
    android:gravity="center"
    android:onClick="onClick"
    android:paddingLeft="5dp"
    android:singleLine="true"
    android:text="提交"
    android:textColor="#ffffffff"
    android:textSize="18dp"
    android:visibility="invisible" /> 

</RelativeLayout> 

定义控制标题栏按钮和标题栏以下内容的布局

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical" > 

  <!-- Title --> 

  <include layout="@layout/layout_titlebar" /> 

  <FrameLayout
    android:id="@+id/layout_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#fff" >
  </FrameLayout> 

</LinearLayout>

注：此处使用 <include> 标签引入标题栏，且下方有定义一个空的FrameLayout的布局。

定义TitleActivity控制按钮及布局

package org.gaochun.widget; 

import org.gaochun.ui.R; 

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.FrameLayout;
import android.widget.TextView;
import android.widget.Toast; 

/**
 * @author gao_chun
 * 自定义标题栏
 */
public class TitleActivity extends Activity implements OnClickListener{ 

  //private RelativeLayout mLayoutTitleBar;
  private TextView mTitleTextView;
  private Button mBackwardbButton;
  private Button mForwardButton;
  private FrameLayout mContentLayout; 

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setupViews();  //加载 activity_title 布局 ，并获取标题及两侧按钮
  } 

  private void setupViews() {
    super.setContentView(R.layout.activity_title);
    mTitleTextView = (TextView) findViewById(R.id.text_title);
    mContentLayout = (FrameLayout) findViewById(R.id.layout_content);
    mBackwardbButton = (Button) findViewById(R.id.button_backward);
    mForwardButton = (Button) findViewById(R.id.button_forward);
  } 

  /**
   * 是否显示返回按钮
   * @param backwardResid 文字
   * @param show true则显示
   */
  protected void showBackwardView(int backwardResid, boolean show) {
    if (mBackwardbButton != null) {
      if (show) {
        mBackwardbButton.setText(backwardResid);
        mBackwardbButton.setVisibility(View.VISIBLE);
      } else {
        mBackwardbButton.setVisibility(View.INVISIBLE);
      }
    } // else ignored
  } 

  /**
   * 提供是否显示提交按钮
   * @param forwardResId 文字
   * @param show true则显示
   */
  protected void showForwardView(int forwardResId, boolean show) {
    if (mForwardButton != null) {
      if (show) {
        mForwardButton.setVisibility(View.VISIBLE);
        mForwardButton.setText(forwardResId);
      } else {
        mForwardButton.setVisibility(View.INVISIBLE);
      }
    } // else ignored
  } 

  /**
   * 返回按钮点击后触发
   * @param backwardView
   */
  protected void onBackward(View backwardView) {
    Toast.makeText(this, "点击返回，可在此处调用finish()", Toast.LENGTH_LONG).show();
    //finish();
  } 

  /**
   * 提交按钮点击后触发
   * @param forwardView
   */
  protected void onForward(View forwardView) {
    Toast.makeText(this, "点击提交", Toast.LENGTH_LONG).show();
  } 

  //设置标题内容
  @Override
  public void setTitle(int titleId) {
    mTitleTextView.setText(titleId);
  } 

  //设置标题内容
  @Override
  public void setTitle(CharSequence title) {
    mTitleTextView.setText(title);
  } 

  //设置标题文字颜色
  @Override
  public void setTitleColor(int textColor) {
    mTitleTextView.setTextColor(textColor);
  } 

  //取出FrameLayout并调用父类removeAllViews()方法
  @Override
  public void setContentView(int layoutResID) {
    mContentLayout.removeAllViews();
    View.inflate(this, layoutResID, mContentLayout);
    onContentChanged();
  } 

  @Override
  public void setContentView(View view) {
    mContentLayout.removeAllViews();
    mContentLayout.addView(view);
    onContentChanged();
  } 

  /* (non-Javadoc)
   * @see android.app.Activity#setContentView(android.view.View, android.view.ViewGroup.LayoutParams)
   */
  @Override
  public void setContentView(View view, LayoutParams params) {
    mContentLayout.removeAllViews();
    mContentLayout.addView(view, params);
    onContentChanged();
  } 

  /* (non-Javadoc)
   * @see android.view.View.OnClickListener#onClick(android.view.View)
   * 按钮点击调用的方法
   */
  @Override
  public void onClick(View v) { 

    switch (v.getId()) {
      case R.id.button_backward:
        onBackward(v);
        break; 

      case R.id.button_forward:
        onForward(v);
        break; 

      default:
        break;
    }
  }
}

MainActivity中调用时直接 extends TitleActivity 使用之前在TitleActivity中定义的方法
