Disparar un comando pellizcar in / out al teléfono Android usando adb

Hasta ahora, puedo tocar, deslizar, desbloquear, instalar / desinstalar y ejecutar la aplicación usando los comandos adb, pero no puedo encontrar cómo hacer zoom in / out usando el comando adb.

Tengo las coordenadas de pinch in / out pero no entiendo cómo dispararlas usando el comando adb del terminal.

Por ejemplo, tenemos comando -> entrada de shell adb toque xy Entonces en esto podemos reemplazar xey con valores / coordenadas de forma similar. Quiero saber la manera de simular pinch in / out.

Las coordenadas que obtengo para pinch-in están debajo.

Puedes hacerlo usando adb getevent y sendevent .
Conecte su dispositivo usando adb . Sigue los pasos a continuación.

  1. Identifica tu dispositivo de entrada:
    Abra cualquier imagen en su dispositivo. Para enumerar los dispositivos de entrada, ejecuta

     $ adb shell getevent add device 1: /dev/input/event7 name: "msm8226-tapan9302-snd-card Headset Jack" add device 2: /dev/input/event6 name: "msm8226-tapan9302-snd-card Button Jack" add device 3: /dev/input/event2 name: "synaptics_dsx_i2c" add device 4: /dev/input/event4 name: "qpnp_pon" 

    Pellizque adentro / afuera en la imagen, debería ver algunos registros continuos como

     /dev/input/event2: 0003 0030 00000005 /dev/input/event2: 0000 0000 00000000 /dev/input/event2: 0003 002f 00000000 /dev/input/event2: 0003 0036 00000144 /dev/input/event2: 0003 003a 00000079 /dev/input/event2: 0000 0000 00000000 /dev/input/event2: 0003 0036 00000142 

    Confirma que /dev/input/event2 es el nombre del dispositivo de entrada para mi dispositivo de destino.

  2. Obtenga el getevent exacto y convierta getevent en sendevent :

    Asegúrate de que tu pantalla esté encendida y abierta con alguna imagen,
    Ejecute el siguiente comando en el indicador.

     $ adb shell getevent | grep dev/input/event2 > getevent_input.txt 

    Mientras lo anterior se está ejecutando, pellizque adentro / afuera en la imagen en su teléfono.

    Una vez completado, mata el comando anterior Ctrl + C
    Abra el archivo getevent_input.txt y elimine la primera línea "add device X: /dev/input/eventX" de este.

    Dado que getevent devuelve los valores en decimal, y sendevent toma el valor en hexadecimal.
    Tenemos que hacer la conversión anterior.
    Este script hex_to_dec.py aquí hace el trabajo. Gracias a este chico!

     $./hex_to_dec.py getevent_input.txt 

    Genera un archivo getevent_input.scr , ahora cambia el nombre de este archivo a .sh

     $ mv getevent_input.scr sendevent_input.sh 

    Abra el archivo sendevent_input.sh y elimine la segunda línea "echoing – drawing function" y sendevent_input.sh .

  3. Ejecutar en dispositivo.
    Transfiera sendevent_input.sh al dispositivo.

     $ adb push sendevent_input.sh /sdcard/ 1615 KB/s (64379 bytes in 0.038s) 

    Asegúrese de que su dispositivo tenga una imagen abierta y que la pantalla no esté apagada.

     $ adb shell sh /sdcard/sendevent_input.sh 

Funcionó perfectamente bien para mí, si esto es lo que estás buscando.

Medio ambiente: Motorola Moto G (Android 4.4.4) con ADB (v 1.0.31) en Ubuntu 12.04 .

Una solución (tipo de hacky) con adb shell input ve como

 adb shell input tap 200 200 & PIDTAP=$! sleep 0.1 adb shell input swipe 200 200 200 100 1000 & PIDSWIPE=$! wait $PIDTAP wait $PIDSWIPE 

La idea es que ejecutemos el comando TAP, luego que duerma brevemente y luego realice SWIPE. Tal secuencia de comandos se interpreta como tocar + deslizar para realizar el zoom. El ejemplo anterior sería un alejamiento en un mapa.

“Una (especie de hacky) solución …” funcionó para mí en Ubuntu, pero no pude ejecutar algo similar en Windows. Por lo tanto, he creado un archivo de script (en el teléfono, en / data / local / tmp), pegué ese código allí (omitiendo ‘adb shell’), chmod’ed a u + x, y ejecutado desde Windows a través de adb. Y ahora funciona en el teléfono.
