Android项目中自定义顶部标题栏

Android项目中自定义顶部标题栏

下面给大家详细介绍android中自定义顶部标题栏的思路及实现方式

先来图：

   

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

• 定义控制标题栏按钮和标题栏以下内容的布局

注：此处使用 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.widget.FrameLayout;
import android.widget.TextView;
import android.widget.Toast;

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);

     * 是否显示返回按钮

     */

            } else {

        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

        Toast.makeText(this, "点击返回，可在此处调用finish()", Toast.LENGTH_LONG).show();
        //finish();
    }

    //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
