Android BottomSheet:便捷易用的底部滑出面板(1)

Android BottomSheet是github上的一个第三方开源项目,其主页:https://github.com/Flipboard/bottomsheet

BottomSheet提供了简洁易用的从底部滑出的面板。现在的APP开发,经常需要从底部滑出某些面板提供给用户操作入口,比如最常见的分享,底部滑出一个面板,然后会罗列出多种分享入口,供用户选择。

使用BottomSheet,需要首先在自己的模块build.gradle文件中加入下面代码:

repositories {
jcenter()
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'

compile 'com.flipboard:bottomsheet-core:1.5.1'
compile 'com.flipboard:bottomsheet-commons:1.5.1'
}

如图:



接下来就可以使用BottomSheet。先写布局。用BottomSheet提供的BottomSheetLayout把自己整个页面包裹起来:

<?xml version="1.0" encoding="utf-8"?>
<com.flipboard.bottomsheet.BottomSheetLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/bottomsheet"
android:layout_width="match_parent"
android:layout_height="match_parent">

<LinearLayout
android:id="@+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="16dp">

<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="zhang phil @ csdn"
android:id="@+id/editText" />

<Button
android:id="@+id/share_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end"
android:text="分享" />

</LinearLayout>

</com.flipboard.bottomsheet.BottomSheetLayout>

上层Java代码:

package zhangphil.demo;

import android.content.Context;
import android.content.Intent;
import android.graphics.drawable.Drawable;
import android.support.v4.content.res.ResourcesCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.Button;
import android.widget.EditText;

import com.flipboard.bottomsheet.BottomSheetLayout;
import com.flipboard.bottomsheet.commons.IntentPickerSheetView;

import java.util.Collections;
import java.util.Comparator;

public class MainActivity extends AppCompatActivity {

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

final BottomSheetLayout bottomSheetLayout = (BottomSheetLayout) findViewById(R.id.bottomsheet);
final EditText shareText = (EditText) findViewById(R.id.editText);

Button shareButton = (Button) findViewById(R.id.share_button);
shareButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// 隐藏软键盘
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(shareText.getWindowToken(), 0);

final Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, shareText.getText() + "");
shareIntent.setType("text/plain");

IntentPickerSheetView intentPickerSheet = new IntentPickerSheetView(getApplication(), shareIntent, "分享到...", new IntentPickerSheetView.OnIntentPickedListener() {
@Override
public void onIntentPicked(IntentPickerSheetView.ActivityInfo activityInfo) {
bottomSheetLayout.dismissSheet();
startActivity(activityInfo.getConcreteIntent(shareIntent));
}
});

// 过滤到像系统蓝牙这样的分享模式(可以过滤掉也可以不用过滤)
/*
intentPickerSheet.setFilter(new IntentPickerSheetView.Filter() {
@Override
public boolean include(IntentPickerSheetView.ActivityInfo info) {
return !info.componentName.getPackageName().startsWith("com.android");
}
});
*/

// 排序分享模块
intentPickerSheet.setSortMethod(new Comparator<IntentPickerSheetView.ActivityInfo>() {
@Override
public int compare(IntentPickerSheetView.ActivityInfo lhs, IntentPickerSheetView.ActivityInfo rhs) {
return rhs.label.compareTo(lhs.label);
}
});

// 增加一个自定义的分享选择方式(可选)
Drawable customDrawable = ResourcesCompat.getDrawable(getResources(), R.mipmap.ic_launcher, null);
IntentPickerSheetView.ActivityInfo customInfo = new IntentPickerSheetView.ActivityInfo(customDrawable, "zhang phil custom", getApplicationContext(), MainActivity.class);
intentPickerSheet.setMixins(Collections.singletonList(customInfo));

bottomSheetLayout.showWithSheetView(intentPickerSheet);
}
});
}
}


分享的button按钮触发弹出分享面板,分享面板可以向上拖曳铺满。

代码运行初始化:



点击分享按钮弹出分享面板:



拖曳分享面板向上铺满窗口:
