以下是我的navigation_header.xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/colorPrimary">
<LinearLayout
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="20dp">

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="20dp"
        android:layout_marginRight="@id/textView"
        app:srcCompat="@mipmap/ic_home_white_24dp" />
    <TextView
        android:id="@+id/textView"

        android:text="Home"
        android:textAlignment="center"
        android:textColor="#ffffff"
        android:textSize="17sp" />

</LinearLayout>
</LinearLayout>

Following is my MainActivity.java

package com.example.lenovo.jdstudio;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MenuItem;

public class MainActivity extends AppCompatActivity {

    private DrawerLayout mDrawerLayout ;
    private ActionBarDrawerToggle mToggle;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mDrawerLayout =(DrawerLayout) findViewById(R.id.drawer_layout);
        mToggle = new ActionBarDrawerToggle(this,mDrawerLayout,R.string.open,R.string.close);

        mDrawerLayout.addDrawerListener(mToggle);
        mToggle.syncState();

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if(mToggle.onOptionsItemSelected(item))
        {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

Answer 1

试试这从你的android:layout_marginRight="@id/textView"删除ImageView并在DP中应用保证金

<ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="20dp"
        android:layout_marginRight="20dp"
        app:srcCompat="@mipmap/ic_home_white_24dp" />

Answer 2

你在保证金上推出了视图ID，将dp放在保证金上可以解决你的问题
