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:




    

        

        


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() {
                    @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。
