Question

我的协调器布局xml有问题，它来自详细活动类。我不知道是否点击RecyclerView的项目，然后我的应用程序强制关闭..请告诉我我的班级和我的xml有什么问题。

此处是详细信息类的代码

public class DetailActivity extends AppCompatActivity {

    private CoordinatorLayout coordinatorLayout;
    private CollapsingToolbarLayout collapsingToolbarLayout;
    private Toolbar toolbar;

    TextView nameTxt,propTxt,descTxt;
    ImageView img;

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

        Intent i=this.getIntent();
        String name=i.getExtras().getString("NAME_KEY");
        String propellant=i.getExtras().getString("PROPELLANT_KEY");
        String desc=i.getExtras().getString("DESCRIPTION_KEY");
        String imageurl=i.getExtras().getString("IMAGEURL_KEY");

        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        initToolbar();

        coordinatorLayout =(CoordinatorLayout) findViewById(R.id.coordinator);
        collapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.maincollapsing);
        collapsingToolbarLayout.setTitle("NAME_KEY");

        nameTxt= (TextView) findViewById(R.id.nameTxtDetail);
        propTxt= (TextView) findViewById(R.id.propellantTxtDetail);
        descTxt= (TextView) findViewById(R.id.descDetailTxt);
        img= (ImageView) findViewById(R.id.mainbackdrop);

        nameTxt.setText(name);
        propTxt.setText(propellant);
        descTxt.setText(Html.fromHtml(desc));
        PicassoClient.downloadImage(this,imageurl,img);
    }

    private void initToolbar(){
        toolbar = (Toolbar) findViewById(R.id.maintoolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.sample_actions, menu);
        return true;
    }

}

这是我的xml代码：

Answer 1

你打电话的原因之一

setSupportActionBar(toolbar);

前

initToolbar();

实际上你在onCreate和initToolbar（）中两次调用setSupportActionBar（工具栏）
执行此操作。从onCreate中删除setSupportActionBar（toolbar）和getSupportActionBar（）。setDisplayHomeAsUpEnabled（true） / p>
